[SERIAL] Clean up and fix tty transmission start/stoping
The start_tx and stop_tx methods were passed a flag to indicate
whether the start/stop was from the tty start/stop callbacks, and
some drivers used this flag to decide whether to ask the UART to
immediately stop transmission (where the UART supports such a
feature.)
There are other cases when we wish this to occur - when CTS is
lowered, or if we change from soft to hard flow control and CTS
is inactive. In these cases, this flag was false, and we would
allow the transmitter to drain before stopping.
There is really only one case where we want to let the transmitter
drain before disabling, and that's when we run out of characters
to send.
Hence, re-jig the start_tx and stop_tx methods to eliminate this
flag, and introduce new functions for the special "disable and
allow transmitter to drain" case.

+ S3C24XX USB Host support
+ ========================
+
+
+
+Introduction
+------------
+
+ This document details the S3C2410/S3C2440 in-built OHCI USB host support.
+
+Configuration
+-------------
+
+ Enable at least the following kernel options:
+
+ menuconfig:
+
+ Device Drivers --->
+ USB support --->
+ <*> Support for Host-side USB
+ <*> OHCI HCD support
+
+
+ .config:
+ CONFIG_USB
+ CONFIG_USB_OHCI_HCD
+
+
+ Once these options are configured, the standard set of USB device
+ drivers can be configured and used.
+
+
+Board Support
+-------------
+
+ The driver attaches to a platform device, which will need to be
+ added by the board specific support file in linux/arch/arm/mach-s3c2410,
+ such as mach-bast.c or mach-smdk2410.c
+
+ The platform device's platform_data field is only needed if the
+ board implements extra power control or over-current monitoring.
+
+ The OHCI driver does not ensure the state of the S3C2410's MISCCTRL
+ register, so if both ports are to be used for the host, then it is
+ the board support file's responsibility to ensure that the second
+ port is configured to be connected to the OHCI core.
+
+
+Platform Data
+-------------
+
+ See linux/include/asm-arm/arch-s3c2410/usb-control.h for the
+ descriptions of the platform device data. An implementation
+ can be found in linux/arch/arm/mach-s3c2410/usb-simtec.c .
+
+ The `struct s3c2410_hcd_info` contains a pair of functions
+ that get called to enable over-current detection, and to
+ control the port power status.
+
+ The ports are numbered 0 and 1.
+
+ power_control:
+
+ Called to enable or disable the power on the port.
+
+ enable_oc:
+
+ Called to enable or disable the over-current monitoring.
+ This should claim or release the resources being used to
+ check the power condition on the port, such as an IRQ.
+
+ report_oc:
+
+ The OHCI driver fills this field in for the over-current code
+ to call when there is a change to the over-current state on
+ an port. The ports argument is a bitmask of 1 bit per port,
+ with bit X being 1 for an over-current on port X.
+
+ The function s3c2410_usb_report_oc() has been provided to
+ ensure this is called correctly.
+
+ port[x]:
+
+ This is struct describes each port, 0 or 1. The platform driver
+ should set the flags field of each port to S3C_HCDFLG_USED if
+ the port is enabled.

+
+1. Concepts: Kprobes, Jprobes, Return Probes
+
+Kprobes enables you to dynamically break into any kernel routine and
+collect debugging and performance information non-disruptively. You
+can trap at almost any kernel code address, specifying a handler
+routine to be invoked when the breakpoint is hit.
+
+There are currently three types of probes: kprobes, jprobes, and
+kretprobes (also called return probes). A kprobe can be inserted
+on virtually any instruction in the kernel. A jprobe is inserted at
+the entry to a kernel function, and provides convenient access to the
+function's arguments. A return probe fires when a specified function
+returns.
+
+In the typical case, Kprobes-based instrumentation is packaged as
+a kernel module. The module's init function installs ("registers")
+one or more probes, and the exit function unregisters them. A
+registration function such as register_kprobe() specifies where
+the probe is to be inserted and what handler is to be called when
+the probe is hit.
+
+The next three subsections explain how the different types of
+probes work. They explain certain things that you'll need to
+know in order to make the best use of Kprobes -- e.g., the
+difference between a pre_handler and a post_handler, and how
+to use the maxactive and nmissed fields of a kretprobe. But
+if you're in a hurry to start using Kprobes, you can skip ahead
+to section 2.
+
+1.1 How Does a Kprobe Work?
+
+When a kprobe is registered, Kprobes makes a copy of the probed
+instruction and replaces the first byte(s) of the probed instruction
+with a breakpoint instruction (e.g., int3 on i386 and x86_64).
+
+When a CPU hits the breakpoint instruction, a trap occurs, the CPU's
+registers are saved, and control passes to Kprobes via the
+notifier_call_chain mechanism. Kprobes executes the "pre_handler"
+associated with the kprobe, passing the handler the addresses of the
+kprobe struct and the saved registers.
+
+Next, Kprobes single-steps its copy of the probed instruction.
+(It would be simpler to single-step the actual instruction in place,
+but then Kprobes would have to temporarily remove the breakpoint
+instruction. This would open a small time window when another CPU
+could sail right past the probepoint.)
+
+After the instruction is single-stepped, Kprobes executes the
+"post_handler," if any, that is associated with the kprobe.
+Execution then continues with the instruction following the probepoint.
+
+1.2 How Does a Jprobe Work?
+
+A jprobe is implemented using a kprobe that is placed on a function's
+entry point. It employs a simple mirroring principle to allow
+seamless access to the probed function's arguments. The jprobe
+handler routine should have the same signature (arg list and return
+type) as the function being probed, and must always end by calling
+the Kprobes function jprobe_return().
+
+Here's how it works. When the probe is hit, Kprobes makes a copy of
+the saved registers and a generous portion of the stack (see below).
+Kprobes then points the saved instruction pointer at the jprobe's
+handler routine, and returns from the trap. As a result, control
+passes to the handler, which is presented with the same register and
+stack contents as the probed function. When it is done, the handler
+calls jprobe_return(), which traps again to restore the original stack
+contents and processor state and switch to the probed function.
+
+By convention, the callee owns its arguments, so gcc may produce code
+that unexpectedly modifies that portion of the stack. This is why
+Kprobes saves a copy of the stack and restores it after the jprobe
+handler has run. Up to MAX_STACK_SIZE bytes are copied -- e.g.,
+64 bytes on i386.
+
+Note that the probed function's args may be passed on the stack
+or in registers (e.g., for x86_64 or for an i386 fastcall function).
+The jprobe will work in either case, so long as the handler's
+prototype matches that of the probed function.
+
+1.3 How Does a Return Probe Work?
+
+When you call register_kretprobe(), Kprobes establishes a kprobe at
+the entry to the function. When the probed function is called and this
+probe is hit, Kprobes saves a copy of the return address, and replaces
+the return address with the address of a "trampoline." The trampoline
+is an arbitrary piece of code -- typically just a nop instruction.
+At boot time, Kprobes registers a kprobe at the trampoline.
+
+When the probed function executes its return instruction, control
+passes to the trampoline and that probe is hit. Kprobes' trampoline
+handler calls the user-specified handler associated with the kretprobe,
+then sets the saved instruction pointer to the saved return address,
+and that's where execution resumes upon return from the trap.
+
+While the probed function is executing, its return address is
+stored in an object of type kretprobe_instance. Before calling
+register_kretprobe(), the user sets the maxactive field of the
+kretprobe struct to specify how many instances of the specified
+function can be probed simultaneously. register_kretprobe()
+pre-allocates the indicated number of kretprobe_instance objects.
+
+For example, if the function is non-recursive and is called with a
+spinlock held, maxactive = 1 should be enough. If the function is
+non-recursive and can never relinquish the CPU (e.g., via a semaphore
+or preemption), NR_CPUS should be enough. If maxactive <= 0, it is
+set to a default value. If CONFIG_PREEMPT is enabled, the default
+is max(10, 2*NR_CPUS). Otherwise, the default is NR_CPUS.
+
+It's not a disaster if you set maxactive too low; you'll just miss
+some probes. In the kretprobe struct, the nmissed field is set to
+zero when the return probe is registered, and is incremented every
+time the probed function is entered but there is no kretprobe_instance
+object available for establishing the return probe.
+
+2. Architectures Supported
+
+Kprobes, jprobes, and return probes are implemented on the following
+architectures:
+
+- i386
+- x86_64 (AMD-64, E64MT)
+- ppc64
+- ia64 (Support for probes on certain instruction types is still in progress.)
+- sparc64 (Return probes not yet implemented.)
+
+3. Configuring Kprobes
+
+When configuring the kernel using make menuconfig/xconfig/oldconfig,
+ensure that CONFIG_KPROBES is set to "y". Under "Kernel hacking",
+look for "Kprobes". You may have to enable "Kernel debugging"
+(CONFIG_DEBUG_KERNEL) before you can enable Kprobes.
+
+You may also want to ensure that CONFIG_KALLSYMS and perhaps even
+CONFIG_KALLSYMS_ALL are set to "y", since kallsyms_lookup_name()
+is a handy, version-independent way to find a function's address.
+
+If you need to insert a probe in the middle of a function, you may find
+it useful to "Compile the kernel with debug info" (CONFIG_DEBUG_INFO),
+so you can use "objdump -d -l vmlinux" to see the source-to-object
+code mapping.
+
+4. API Reference
+
+The Kprobes API includes a "register" function and an "unregister"
+function for each type of probe. Here are terse, mini-man-page
+specifications for these functions and the associated probe handlers
+that you'll write. See the latter half of this document for examples.
+
+4.1 register_kprobe
+
+#include <linux/kprobes.h>
+int register_kprobe(struct kprobe *kp);
+
+Sets a breakpoint at the address kp->addr. When the breakpoint is
+hit, Kprobes calls kp->pre_handler. After the probed instruction
+is single-stepped, Kprobe calls kp->post_handler. If a fault
+occurs during execution of kp->pre_handler or kp->post_handler,
+or during single-stepping of the probed instruction, Kprobes calls
+kp->fault_handler. Any or all handlers can be NULL.
+
+register_kprobe() returns 0 on success, or a negative errno otherwise.
+
+User's pre-handler (kp->pre_handler):
+#include <linux/kprobes.h>
+#include <linux/ptrace.h>
+int pre_handler(struct kprobe *p, struct pt_regs *regs);
+
+Called with p pointing to the kprobe associated with the breakpoint,
+and regs pointing to the struct containing the registers saved when
+the breakpoint was hit. Return 0 here unless you're a Kprobes geek.
+
+User's post-handler (kp->post_handler):
+#include <linux/kprobes.h>
+#include <linux/ptrace.h>
+void post_handler(struct kprobe *p, struct pt_regs *regs,
+ unsigned long flags);
+
+p and regs are as described for the pre_handler. flags always seems
+to be zero.
+
+User's fault-handler (kp->fault_handler):
+#include <linux/kprobes.h>
+#include <linux/ptrace.h>
+int fault_handler(struct kprobe *p, struct pt_regs *regs, int trapnr);
+
+p and regs are as described for the pre_handler. trapnr is the
+architecture-specific trap number associated with the fault (e.g.,
+on i386, 13 for a general protection fault or 14 for a page fault).
+Returns 1 if it successfully handled the exception.
+
+4.2 register_jprobe
+
+#include <linux/kprobes.h>
+int register_jprobe(struct jprobe *jp)
+
+Sets a breakpoint at the address jp->kp.addr, which must be the address
+of the first instruction of a function. When the breakpoint is hit,
+Kprobes runs the handler whose address is jp->entry.
+
+The handler should have the same arg list and return type as the probed
+function; and just before it returns, it must call jprobe_return().
+(The handler never actually returns, since jprobe_return() returns
+control to Kprobes.) If the probed function is declared asmlinkage,
+fastcall, or anything else that affects how args are passed, the
+handler's declaration must match.
+
+register_jprobe() returns 0 on success, or a negative errno otherwise.
+
+4.3 register_kretprobe
+
+#include <linux/kprobes.h>
+int register_kretprobe(struct kretprobe *rp);
+
+Establishes a return probe for the function whose address is
+rp->kp.addr. When that function returns, Kprobes calls rp->handler.
+You must set rp->maxactive appropriately before you call
+register_kretprobe(); see "How Does a Return Probe Work?" for details.
+
+register_kretprobe() returns 0 on success, or a negative errno
+otherwise.
+
+User's return-probe handler (rp->handler):
+#include <linux/kprobes.h>
+#include <linux/ptrace.h>
+int kretprobe_handler(struct kretprobe_instance *ri, struct pt_regs *regs);
+
+regs is as described for kprobe.pre_handler. ri points to the
+kretprobe_instance object, of which the following fields may be
+of interest:
+- ret_addr: the return address
+- rp: points to the corresponding kretprobe object
+- task: points to the corresponding task struct
+The handler's return value is currently ignored.
+
+4.4 unregister_*probe
+
+#include <linux/kprobes.h>
+void unregister_kprobe(struct kprobe *kp);
+void unregister_jprobe(struct jprobe *jp);
+void unregister_kretprobe(struct kretprobe *rp);
+
+Removes the specified probe. The unregister function can be called
+at any time after the probe has been registered.
+
+5. Kprobes Features and Limitations
+
+As of Linux v2.6.12, Kprobes allows multiple probes at the same
+address. Currently, however, there cannot be multiple jprobes on
+the same function at the same time.
+
+In general, you can install a probe anywhere in the kernel.
+In particular, you can probe interrupt handlers. Known exceptions
+are discussed in this section.
+
+For obvious reasons, it's a bad idea to install a probe in
+the code that implements Kprobes (mostly kernel/kprobes.c and
+arch/*/kernel/kprobes.c). A patch in the v2.6.13 timeframe instructs
+Kprobes to reject such requests.
+
+If you install a probe in an inline-able function, Kprobes makes
+no attempt to chase down all inline instances of the function and
+install probes there. gcc may inline a function without being asked,
+so keep this in mind if you're not seeing the probe hits you expect.
+
+A probe handler can modify the environment of the probed function
+-- e.g., by modifying kernel data structures, or by modifying the
+contents of the pt_regs struct (which are restored to the registers
+upon return from the breakpoint). So Kprobes can be used, for example,
+to install a bug fix or to inject faults for testing. Kprobes, of
+course, has no way to distinguish the deliberately injected faults
+from the accidental ones. Don't drink and probe.
+
+Kprobes makes no attempt to prevent probe handlers from stepping on
+each other -- e.g., probing printk() and then calling printk() from a
+probe handler. As of Linux v2.6.12, if a probe handler hits a probe,
+that second probe's handlers won't be run in that instance.
+
+In Linux v2.6.12 and previous versions, Kprobes' data structures are
+protected by a single lock that is held during probe registration and
+unregistration and while handlers are run. Thus, no two handlers
+can run simultaneously. To improve scalability on SMP systems,
+this restriction will probably be removed soon, in which case
+multiple handlers (or multiple instances of the same handler) may
+run concurrently on different CPUs. Code your handlers accordingly.
+
+Kprobes does not use semaphores or allocate memory except during
+registration and unregistration.
+
+Probe handlers are run with preemption disabled. Depending on the
+architecture, handlers may also run with interrupts disabled. In any
+case, your handler should not yield the CPU (e.g., by attempting to
+acquire a semaphore).
+
+Since a return probe is implemented by replacing the return
+address with the trampoline's address, stack backtraces and calls
+to __builtin_return_address() will typically yield the trampoline's
+address instead of the real return address for kretprobed functions.
+(As far as we can tell, __builtin_return_address() is used only
+for instrumentation and error reporting.)
+
+If the number of times a function is called does not match the
+number of times it returns, registering a return probe on that
+function may produce undesirable results. We have the do_exit()
+and do_execve() cases covered. do_fork() is not an issue. We're
+unaware of other specific cases where this could be a problem.
+
+6. Probe Overhead
+
+On a typical CPU in use in 2005, a kprobe hit takes 0.5 to 1.0
+microseconds to process. Specifically, a benchmark that hits the same
+probepoint repeatedly, firing a simple handler each time, reports 1-2
+million hits per second, depending on the architecture. A jprobe or
+return-probe hit typically takes 50-75% longer than a kprobe hit.
+When you have a return probe set on a function, adding a kprobe at
+the entry to that function adds essentially no overhead.
+
+Here are sample overhead figures (in usec) for different architectures.
+k = kprobe; j = jprobe; r = return probe; kr = kprobe + return probe
+on same function; jr = jprobe + return probe on same function
+
+i386: Intel Pentium M, 1495 MHz, 2957.31 bogomips
+k = 0.57 usec; j = 1.00; r = 0.92; kr = 0.99; jr = 1.40
+
+x86_64: AMD Opteron 246, 1994 MHz, 3971.48 bogomips
+k = 0.49 usec; j = 0.76; r = 0.80; kr = 0.82; jr = 1.07
+
+ppc64: POWER5 (gr), 1656 MHz (SMT disabled, 1 virtual CPU per physical CPU)
+k = 0.77 usec; j = 1.31; r = 1.26; kr = 1.45; jr = 1.99
+
+7. TODO
+
+a. SystemTap (http://sourceware.org/systemtap): Work in progress
+to provide a simplified programming interface for probe-based
+instrumentation.
+b. Improved SMP scalability: Currently, work is in progress to handle
+multiple kprobes in parallel.
+c. Kernel return probes for sparc64.
+d. Support for other architectures.
+e. User-space probes.
+
+8. Kprobes Example
+
+Here's a sample kernel module showing the use of kprobes to dump a
+stack trace and selected i386 registers when do_fork() is called.

+ Chelsio N210 10Gb Ethernet Network Controller
+
+ Driver Release Notes for Linux
+
+ Version 2.1.1
+
+ June 20, 2005
+
+CONTENTS
+========
+ INTRODUCTION
+ FEATURES
+ PERFORMANCE
+ DRIVER MESSAGES
+ KNOWN ISSUES
+ SUPPORT
+
+
+INTRODUCTION
+============
+
+ This document describes the Linux driver for Chelsio 10Gb Ethernet Network
+ Controller. This driver supports the Chelsio N210 NIC and is backward
+ compatible with the Chelsio N110 model 10Gb NICs.
+
+
+FEATURES
+========
+
+ Adaptive Interrupts (adaptive-rx)
+ ---------------------------------
+
+ This feature provides an adaptive algorithm that adjusts the interrupt
+ coalescing parameters, allowing the driver to dynamically adapt the latency
+ settings to achieve the highest performance during various types of network
+ load.
+
+ The interface used to control this feature is ethtool. Please see the
+ ethtool manpage for additional usage information.
+
+ By default, adaptive-rx is disabled.
+ To enable adaptive-rx:
+
+ ethtool -C <interface> adaptive-rx on
+
+ To disable adaptive-rx, use ethtool:
+
+ ethtool -C <interface> adaptive-rx off
+
+ After disabling adaptive-rx, the timer latency value will be set to 50us.
+ You may set the timer latency after disabling adaptive-rx:
+
+ ethtool -C <interface> rx-usecs <microseconds>
+
+ An example to set the timer latency value to 100us on eth0:
+
+ ethtool -C eth0 rx-usecs 100
+
+ You may also provide a timer latency value while disabling adpative-rx:
+
+ ethtool -C <interface> adaptive-rx off rx-usecs <microseconds>
+
+ If adaptive-rx is disabled and a timer latency value is specified, the timer
+ will be set to the specified value until changed by the user or until
+ adaptive-rx is enabled.
+
+ To view the status of the adaptive-rx and timer latency values:
+
+ ethtool -c <interface>
+
+
+ TCP Segmentation Offloading (TSO) Support
+ -----------------------------------------
+
+ This feature, also known as "large send", enables a system's protocol stack
+ to offload portions of outbound TCP processing to a network interface card
+ thereby reducing system CPU utilization and enhancing performance.
+
+ The interface used to control this feature is ethtool version 1.8 or higher.
+ Please see the ethtool manpage for additional usage information.
+
+ By default, TSO is enabled.
+ To disable TSO:
+
+ ethtool -K <interface> tso off
+
+ To enable TSO:
+
+ ethtool -K <interface> tso on
+
+ To view the status of TSO:
+
+ ethtool -k <interface>
+
+
+PERFORMANCE
+===========
+
+ The following information is provided as an example of how to change system
+ parameters for "performance tuning" an what value to use. You may or may not
+ want to change these system parameters, depending on your server/workstation
+ application. Doing so is not warranted in any way by Chelsio Communications,
+ and is done at "YOUR OWN RISK". Chelsio will not be held responsible for loss
+ of data or damage to equipment.
+
+ Your distribution may have a different way of doing things, or you may prefer
+ a different method. These commands are shown only to provide an example of
+ what to do and are by no means definitive.
+
+ Making any of the following system changes will only last until you reboot
+ your system. You may want to write a script that runs at boot-up which
+ includes the optimal settings for your system.
+
+ Setting PCI Latency Timer:
+ setpci -d 1425:* 0x0c.l=0x0000F800
+
+ Disabling TCP timestamp:
+ sysctl -w net.ipv4.tcp_timestamps=0
+
+ Disabling SACK:
+ sysctl -w net.ipv4.tcp_sack=0
+
+ Setting large number of incoming connection requests:
+ sysctl -w net.ipv4.tcp_max_syn_backlog=3000
+
+ Setting maximum receive socket buffer size:
+ sysctl -w net.core.rmem_max=1024000
+
+ Setting maximum send socket buffer size:
+ sysctl -w net.core.wmem_max=1024000
+
+ Set smp_affinity (on a multiprocessor system) to a single CPU:
+ echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+ Setting default receive socket buffer size:
+ sysctl -w net.core.rmem_default=524287
+
+ Setting default send socket buffer size:
+ sysctl -w net.core.wmem_default=524287
+
+ Setting maximum option memory buffers:
+ sysctl -w net.core.optmem_max=524287
+
+ Setting maximum backlog (# of unprocessed packets before kernel drops):
+ sysctl -w net.core.netdev_max_backlog=300000
+
+ Setting TCP read buffers (min/default/max):
+ sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
+
+ Setting TCP write buffers (min/pressure/max):
+ sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
+
+ Setting TCP buffer space (min/pressure/max):
+ sysctl -w net.ipv4.tcp_mem="10000000 10000000 10000000"
+
+ TCP window size for single connections:
+ The receive buffer (RX_WINDOW) size must be at least as large as the
+ Bandwidth-Delay Product of the communication link between the sender and
+ receiver. Due to the variations of RTT, you may want to increase the buffer
+ size up to 2 times the Bandwidth-Delay Product. Reference page 289 of
+ "TCP/IP Illustrated, Volume 1, The Protocols" by W. Richard Stevens.
+ At 10Gb speeds, use the following formula:
+ RX_WINDOW >= 1.25MBytes * RTT(in milliseconds)
+ Example for RTT with 100us: RX_WINDOW = (1,250,000 * 0.1) = 125,000
+ RX_WINDOW sizes of 256KB - 512KB should be sufficient.
+ Setting the min, max, and default receive buffer (RX_WINDOW) size:
+ sysctl -w net.ipv4.tcp_rmem="<min> <default> <max>"
+
+ TCP window size for multiple connections:
+ The receive buffer (RX_WINDOW) size may be calculated the same as single
+ connections, but should be divided by the number of connections. The
+ smaller window prevents congestion and facilitates better pacing,
+ especially if/when MAC level flow control does not work well or when it is
+ not supported on the machine. Experimentation may be necessary to attain
+ the correct value. This method is provided as a starting point fot the
+ correct receive buffer size.
+ Setting the min, max, and default receive buffer (RX_WINDOW) size is
+ performed in the same manner as single connection.
+
+

+
+
+KNOWN ISSUES
+============
+
+ These issues have been identified during testing. The following information
+ is provided as a workaround to the problem. In some cases, this problem is
+ inherent to Linux or to a particular Linux Distribution and/or hardware
+ platform.
+
+ 1. Large number of TCP retransmits on a multiprocessor (SMP) system.
+
+ On a system with multiple CPUs, the interrupt (IRQ) for the network
+ controller may be bound to more than one CPU. This will cause TCP
+ retransmits if the packet data were to be split across different CPUs
+ and re-assembled in a different order than expected.
+
+ To eliminate the TCP retransmits, set smp_affinity on the particular
+ interrupt to a single CPU. You can locate the interrupt (IRQ) used on
+ the N110/N210 by using ifconfig:
+ ifconfig <dev_name> | grep Interrupt
+ Set the smp_affinity to a single CPU:
+ echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+ It is highly suggested that you do not run the irqbalance daemon on your
+ system, as this will change any smp_affinity setting you have applied.
+ The irqbalance daemon runs on a 10 second interval and binds interrupts
+ to the least loaded CPU determined by the daemon. To disable this daemon:
+ chkconfig --level 2345 irqbalance off
+
+ By default, some Linux distributions enable the kernel feature,
+ irqbalance, which performs the same function as the daemon. To disable
+ this feature, add the following line to your bootloader:
+ noirqbalance
+
+ Example using the Grub bootloader:
+ title Red Hat Enterprise Linux AS (2.4.21-27.ELsmp)
+ root (hd0,0)
+ kernel /vmlinuz-2.4.21-27.ELsmp ro root=/dev/hda3 noirqbalance
+ initrd /initrd-2.4.21-27.ELsmp.img
+
+ 2. After running insmod, the driver is loaded and the incorrect network
+ interface is brought up without running ifup.
+
+ When using 2.4.x kernels, including RHEL kernels, the Linux kernel
+ invokes a script named "hotplug". This script is primarily used to
+ automatically bring up USB devices when they are plugged in, however,
+ the script also attempts to automatically bring up a network interface
+ after loading the kernel module. The hotplug script does this by scanning
+ the ifcfg-eth# config files in /etc/sysconfig/network-scripts, looking
+ for HWADDR=<mac_address>.
+
+ If the hotplug script does not find the HWADDRR within any of the
+ ifcfg-eth# files, it will bring up the device with the next available
+ interface name. If this interface is already configured for a different
+ network card, your new interface will have incorrect IP address and
+ network settings.
+
+ To solve this issue, you can add the HWADDR=<mac_address> key to the
+ interface config file of your network controller.
+
+ To disable this "hotplug" feature, you may add the driver (module name)
+ to the "blacklist" file located in /etc/hotplug. It has been noted that
+ this does not work for network devices because the net.agent script
+ does not use the blacklist file. Simply remove, or rename, the net.agent
+ script located in /etc/hotplug to disable this feature.
+
+ 3. Transport Protocol (TP) hangs when running heavy multi-connection traffic
+ on an AMD Opteron system with HyperTransport PCI-X Tunnel chipset.
+
+ If your AMD Opteron system uses the AMD-8131 HyperTransport PCI-X Tunnel
+ chipset, you may experience the "133-Mhz Mode Split Completion Data
+ Corruption" bug identified by AMD while using a 133Mhz PCI-X card on the
+ bus PCI-X bus.
+
+ AMD states, "Under highly specific conditions, the AMD-8131 PCI-X Tunnel
+ can provide stale data via split completion cycles to a PCI-X card that
+ is operating at 133 Mhz", causing data corruption.
+
+ AMD's provides three workarounds for this problem, however, Chelsio
+ recommends the first option for best performance with this bug:
+
+ For 133Mhz secondary bus operation, limit the transaction length and
+ the number of outstanding transactions, via BIOS configuration
+ programming of the PCI-X card, to the following:
+
+ Data Length (bytes): 1k
+ Total allowed outstanding transactions: 2
+
+ Please refer to AMD 8131-HT/PCI-X Errata 26310 Rev 3.08 August 2004,
+ section 56, "133-MHz Mode Split Completion Data Corruption" for more
+ details with this bug and workarounds suggested by AMD.
+
+ It may be possible to work outside AMD's recommended PCI-X settings, try
+ increasing the Data Length to 2k bytes for increased performance. If you
+ have issues with these settings, please revert to the "safe" settings
+ and duplicate the problem before submitting a bug or asking for support.
+
+ NOTE: The default setting on most systems is 8 outstanding transactions
+ and 2k bytes data length.
+
+ 4. On multiprocessor systems, it has been noted that an application which
+ is handling 10Gb networking can switch between CPUs causing degraded
+ and/or unstable performance.
+
+ If running on an SMP system and taking performance measurements, it
+ is suggested you either run the latest netperf-2.4.0+ or use a binding
+ tool such as Tim Hockin's procstate utilities (runon)
+ <http://www.hockin.org/~thockin/procstate/>.
+
+ Binding netserver and netperf (or other applications) to particular
+ CPUs will have a significant difference in performance measurements.
+ You may need to experiment which CPU to bind the application to in
+ order to achieve the best performance for your system.
+
+ If you are developing an application designed for 10Gb networking,
+ please keep in mind you may want to look at kernel functions
+ sched_setaffinity & sched_getaffinity to bind your application.
+
+ If you are just running user-space applications such as ftp, telnet,
+ etc., you may want to try the runon tool provided by Tim Hockin's
+ procstate utility. You could also try binding the interface to a
+ particular CPU: runon 0 ifup eth0

+PHY Abstraction Layer
+(Updated 2005-07-21)
+
+Purpose
+
+ Most network devices consist of set of registers which provide an interface
+ to a MAC layer, which communicates with the physical connection through a
+ PHY. The PHY concerns itself with negotiating link parameters with the link
+ partner on the other side of the network connection (typically, an ethernet
+ cable), and provides a register interface to allow drivers to determine what
+ settings were chosen, and to configure what settings are allowed.
+
+ While these devices are distinct from the network devices, and conform to a
+ standard layout for the registers, it has been common practice to integrate
+ the PHY management code with the network driver. This has resulted in large
+ amounts of redundant code. Also, on embedded systems with multiple (and
+ sometimes quite different) ethernet controllers connected to the same
+ management bus, it is difficult to ensure safe use of the bus.
+
+ Since the PHYs are devices, and the management busses through which they are
+ accessed are, in fact, busses, the PHY Abstraction Layer treats them as such.
+ In doing so, it has these goals:
+
+ 1) Increase code-reuse
+ 2) Increase overall code-maintainability
+ 3) Speed development time for new network drivers, and for new systems
+
+ Basically, this layer is meant to provide an interface to PHY devices which
+ allows network driver writers to write as little code as possible, while
+ still providing a full feature set.
+
+The MDIO bus
+
+ Most network devices are connected to a PHY by means of a management bus.
+ Different devices use different busses (though some share common interfaces).
+ In order to take advantage of the PAL, each bus interface needs to be
+ registered as a distinct device.
+
+ 1) read and write functions must be implemented. Their prototypes are:
+
+ int write(struct mii_bus *bus, int mii_id, int regnum, u16 value);
+ int read(struct mii_bus *bus, int mii_id, int regnum);
+
+ mii_id is the address on the bus for the PHY, and regnum is the register
+ number. These functions are guaranteed not to be called from interrupt
+ time, so it is safe for them to block, waiting for an interrupt to signal
+ the operation is complete
+
+ 2) A reset function is necessary. This is used to return the bus to an
+ initialized state.
+
+ 3) A probe function is needed. This function should set up anything the bus
+ driver needs, setup the mii_bus structure, and register with the PAL using
+ mdiobus_register. Similarly, there's a remove function to undo all of
+ that (use mdiobus_unregister).
+
+ 4) Like any driver, the device_driver structure must be configured, and init
+ exit functions are used to register the driver.
+
+ 5) The bus must also be declared somewhere as a device, and registered.
+
+ As an example for how one driver implemented an mdio bus driver, see
+ drivers/net/gianfar_mii.c and arch/ppc/syslib/mpc85xx_devices.c
+
+Connecting to a PHY
+
+ Sometime during startup, the network driver needs to establish a connection
+ between the PHY device, and the network device. At this time, the PHY's bus
+ and drivers need to all have been loaded, so it is ready for the connection.
+ At this point, there are several ways to connect to the PHY:
+
+ 1) The PAL handles everything, and only calls the network driver when
+ the link state changes, so it can react.
+
+ 2) The PAL handles everything except interrupts (usually because the
+ controller has the interrupt registers).
+
+ 3) The PAL handles everything, but checks in with the driver every second,
+ allowing the network driver to react first to any changes before the PAL
+ does.
+
+ 4) The PAL serves only as a library of functions, with the network device
+ manually calling functions to update status, and configure the PHY
+
+
+Letting the PHY Abstraction Layer do Everything
+
+ If you choose option 1 (The hope is that every driver can, but to still be
+ useful to drivers that can't), connecting to the PHY is simple:
+
+ First, you need a function to react to changes in the link state. This
+ function follows this protocol:
+
+ static void adjust_link(struct net_device *dev);
+
+ Next, you need to know the device name of the PHY connected to this device.
+ The name will look something like, "phy0:0", where the first number is the
+ bus id, and the second is the PHY's address on that bus.
+
+ Now, to connect, just call this function:
+
+ phydev = phy_connect(dev, phy_name, &adjust_link, flags);
+
+ phydev is a pointer to the phy_device structure which represents the PHY. If
+ phy_connect is successful, it will return the pointer. dev, here, is the
+ pointer to your net_device. Once done, this function will have started the
+ PHY's software state machine, and registered for the PHY's interrupt, if it
+ has one. The phydev structure will be populated with information about the
+ current state, though the PHY will not yet be truly operational at this
+ point.
+
+ flags is a u32 which can optionally contain phy-specific flags.
+ This is useful if the system has put hardware restrictions on
+ the PHY/controller, of which the PHY needs to be aware.
+
+ Now just make sure that phydev->supported and phydev->advertising have any
+ values pruned from them which don't make sense for your controller (a 10/100
+ controller may be connected to a gigabit capable PHY, so you would need to
+ mask off SUPPORTED_1000baseT*). See include/linux/ethtool.h for definitions
+ for these bitfields. Note that you should not SET any bits, or the PHY may
+ get put into an unsupported state.
+
+ Lastly, once the controller is ready to handle network traffic, you call
+ phy_start(phydev). This tells the PAL that you are ready, and configures the
+ PHY to connect to the network. If you want to handle your own interrupts,
+ just set phydev->irq to PHY_IGNORE_INTERRUPT before you call phy_start.
+ Similarly, if you don't want to use interrupts, set phydev->irq to PHY_POLL.
+
+ When you want to disconnect from the network (even if just briefly), you call
+ phy_stop(phydev).
+
+Keeping Close Tabs on the PAL
+
+ It is possible that the PAL's built-in state machine needs a little help to
+ keep your network device and the PHY properly in sync. If so, you can
+ register a helper function when connecting to the PHY, which will be called
+ every second before the state machine reacts to any changes. To do this, you
+ need to manually call phy_attach() and phy_prepare_link(), and then call
+ phy_start_machine() with the second argument set to point to your special
+ handler.
+
+ Currently there are no examples of how to use this functionality, and testing
+ on it has been limited because the author does not have any drivers which use
+ it (they all use option 1). So Caveat Emptor.
+
+Doing it all yourself
+
+ There's a remote chance that the PAL's built-in state machine cannot track
+ the complex interactions between the PHY and your network device. If this is
+ so, you can simply call phy_attach(), and not call phy_start_machine or
+ phy_prepare_link(). This will mean that phydev->state is entirely yours to
+ handle (phy_start and phy_stop toggle between some of the states, so you
+ might need to avoid them).
+
+ An effort has been made to make sure that useful functionality can be
+ accessed without the state-machine running, and most of these functions are
+ descended from functions which did not interact with a complex state-machine.
+ However, again, no effort has been made so far to test running without the
+ state machine, so tryer beware.
+
+ Here is a brief rundown of the functions:
+
+ int phy_read(struct phy_device *phydev, u16 regnum);
+ int phy_write(struct phy_device *phydev, u16 regnum, u16 val);
+
+ Simple read/write primitives. They invoke the bus's read/write function
+ pointers.
+
+ void phy_print_status(struct phy_device *phydev);
+
+ A convenience function to print out the PHY status neatly.
+
+ int phy_clear_interrupt(struct phy_device *phydev);
+ int phy_config_interrupt(struct phy_device *phydev, u32 interrupts);
+
+ Clear the PHY's interrupt, and configure which ones are allowed,
+ respectively. Currently only supports all on, or all off.

+
+
+PHY Device Drivers
+
+ With the PHY Abstraction Layer, adding support for new PHYs is
+ quite easy. In some cases, no work is required at all! However,
+ many PHYs require a little hand-holding to get up-and-running.
+
+Generic PHY driver
+
+ If the desired PHY doesn't have any errata, quirks, or special
+ features you want to support, then it may be best to not add
+ support, and let the PHY Abstraction Layer's Generic PHY Driver
+ do all of the work.
+
+Writing a PHY driver
+
+ If you do need to write a PHY driver, the first thing to do is
+ make sure it can be matched with an appropriate PHY device.
+ This is done during bus initialization by reading the device's
+ UID (stored in registers 2 and 3), then comparing it to each
+ driver's phy_id field by ANDing it with each driver's
+ phy_id_mask field. Also, it needs a name. Here's an example:
+
+ static struct phy_driver dm9161_driver = {
+ .phy_id = 0x0181b880,
+ .name = "Davicom DM9161E",
+ .phy_id_mask = 0x0ffffff0,
+ ...
+ }
+
+ Next, you need to specify what features (speed, duplex, autoneg,
+ etc) your PHY device and driver support. Most PHYs support
+ PHY_BASIC_FEATURES, but you can look in include/mii.h for other
+ features.
+
+ Each driver consists of a number of function pointers:
+
+ config_init: configures PHY into a sane state after a reset.
+ For instance, a Davicom PHY requires descrambling disabled.
+ probe: Does any setup needed by the driver
+ suspend/resume: power management
+ config_aneg: Changes the speed/duplex/negotiation settings
+ read_status: Reads the current speed/duplex/negotiation settings
+ ack_interrupt: Clear a pending interrupt
+ config_intr: Enable or disable interrupts
+ remove: Does any driver take-down
+
+ Of these, only config_aneg and read_status are required to be
+ assigned by the driver code. The rest are optional. Also, it is
+ preferred to use the generic phy driver's versions of these two
+ functions if at all possible: genphy_read_status and
+ genphy_config_aneg. If this is not possible, it is likely that
+ you only need to perform some actions before and after invoking
+ these functions, and so your functions will wrap the generic
+ ones.
+
+ Feel free to look at the Marvell, Cicada, and Davicom drivers in
+ drivers/net/phy/ for examples (the lxt and qsemi drivers have
+ not been tested as of this writing)

+ * As such, the enable set/clear, pending set/clear and active bit

config PCI
bool "PCI support"
help
- Find out whether you have a PCI motherboard. PCI is the name of a
- bus system, i.e. the way the CPU talks to the other stuff inside
- your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
- VESA. If you have PCI, say Y, otherwise N.
-
- The PCI-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, contains valuable
- information about which PCI hardware does work under Linux and which
- doesn't.
+ Real IA-64 machines all have PCI/PCI-X/PCI Express busses. Say Y
+ here unless you are using a simulator without PCI support.

- * refuses to believe that (u32)&x is a constant expression, so will

- * So, we declare hvReleaseData in inline asm instead. We use inline
- * asm, rather than a .S file, because the assembler won't generate
- * the necessary relocation for the LparMap either, unless that symbol
- * is declared in the same source file. Finally, we put the asm in a
- * dummy, attribute-used function, instead of at file scope, because
- * file scope asms don't allow contraints. We want to use the "i"
- * constraints to put sizeof() and offsetof() expressions in there,
- * because including asm/offsets.h in C code then stringifying causes
- * all manner of warnings.

+ * executing instructions until a trap occurs. Therefore, if
+ * interrupts are disabled, the chip can hang forever.
+ *
+ * It used to be believed that the memory barrier had to be
+ * right in the delay slot, but a case has been traced
+ * recently wherein the memory barrier was one instruction
+ * after the branch delay slot and the chip still hung. The
+ * offending sequence was the following in sym_wakeup_done()
+ * of the sym53c8xx_2 driver:
+ *
+ * call sym_ccb_from_dsa, 0
+ * movge %icc, 0, %l0
+ * brz,pn %o0, .LL1303
+ * mov %o0, %l2
+ * membar #LoadLoad
+ *
+ * The branch has to be mispredicted for the bug to occur.
+ * Therefore, we put the memory barrier explicitly into a
+ * "branch always, predicted taken" delay slot to avoid the

+// The ALU instructions register blocks are enumerated according to the order
+// in which fglrx. I assume there is space for 64 instructions, since
+// each block has space for a maximum of 64 DWORDs, and this matches reported
+// native limits.
+//
+// The basic functional block seems to be one MAD for each color and alpha,
+// and an adder that adds all components after the MUL.
+// - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
+// - DP4: Use OUTC_DP4, OUTA_DP4
+// - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
+// - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
+// - CMP: If ARG2 < 0, return ARG1, else return ARG0
+// - FLR: use FRC+MAD
+// - XPD: use MAD+MAD
+// - SGE, SLT: use MAD+CMP
+// - RSQ: use ABS modifier for argument
+// - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP)
+// into color register
+// - apparently, there's no quick DST operation
+// - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
+// - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
+// - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
+//
+// Operand selection
+// First stage selects three sources from the available registers and
+// constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
+// fglrx sorts the three source fields: Registers before constants,
+// lower indices before higher indices; I do not know whether this is necessary.
+// fglrx fills unused sources with "read constant 0"
+// According to specs, you cannot select more than two different constants.
+//
+// Second stage selects the operands from the sources. This is defined in
+// INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
+// zero and one.
+// Swizzling and negation happens in this stage, as well.
+//
+// Important: Color and alpha seem to be mostly separate, i.e. their sources
+// selection appears to be fully independent (the register storage is probably
+// physically split into a color and an alpha section).
+// However (because of the apparent physical split), there is some interaction
+// WRT swizzling. If, for example, you want to load an R component into an
+// Alpha operand, this R component is taken from a *color* source, not from
+// an alpha source. The corresponding register doesn't even have to appear in
+// the alpha sources list. (I hope this alll makes sense to you)
+//
+// Destination selection
+// The destination register index is in FPI1 (color) and FPI3 (alpha) together
+// with enable bits.
+// There are separate enable bits for writing into temporary registers
+// (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_* /DSTA_OUTPUT).
+// You can write to both at once, or not write at all (the same index
+// must be used for both).
+//
+// Note: There is a special form for LRP
+// - Argument order is the same as in ARB_fragment_program.
+// - Operation is MAD
+// - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
+// - Set FPI0/FPI2_SPECIAL_LRP
+// Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */

+ * the PM3393. This information is provided in the
+ * PM3393 datasheet (Issue 2: November 2002)
+ * section 13.1 -- Device Reset.
+ *
+ * The PM3393 has three types of components that are
+ * individually reset:
+ *
+ * DRESETB - Digital circuitry
+ * PL4_ARESETB - PL4 analog circuitry
+ * XAUI_ARESETB - XAUI bus analog circuitry
+ *
+ * Steps to reset PM3393 using RSTB pin:
+ *
+ * 1. Assert RSTB pin low ( write 0 )
+ * 2. Wait at least 1ms to initiate a complete initialization of device.
+ * 3. Wait until all external clocks and REFSEL are stable.
+ * 4. Wait minimum of 1ms. (after external clocks and REFEL are stable)
+ * 5. De-assert RSTB ( write 1 )
+ * 6. Wait until internal timers to expires after ~14ms.
+ * - Allows analog clock synthesizer(PL4CSU) to stabilize to
+ * selected reference frequency before allowing the digital
+ * portion of the device to operate.
+ * 7. Wait at least 200us for XAUI interface to stabilize.
+ * 8. Verify the PM3393 came out of reset successfully.
+ * Set successful reset flag if everything worked else try again
+ * a few more times.

- * This module implements the AX.25 protocol for kernel-based

- * kernel's AX.25 protocol layers, just like slip.c.
- * AX.25 needs to be separated from slip.c while slip.c is no
- * longer a static kernel device since it is a module.
- * This method clears the way to implement other kiss protocols
- * like mkiss smack g8bpq ..... so far only mkiss is implemented.

- * History
- * Jonathan (G4KLX) Fixed to match Linux networking changes - 2.1.15.
- * Matthias (DG2FEF) Added support for FlexNet CRC (on special request)
- * Fixed bug in ax25_close(): dev_lock_wait() was
- * called twice, causing a deadlock.
- * Jeroen (PE1RXQ) Removed old MKISS_MAGIC stuff and calls to
- * MOD_*_USE_COUNT
- * Remove cli() and fix rtnl lock usage.

If you say Y here, a component which captures the USB traffic
between peripheral-specific drivers and HC drivers will be built.
- The USB_MON is similar in spirit and may be compatible with Dave
- Harding's USBMon.
+ For more information, see <file:Documentation/usb/usbmon.txt>.
- This is somewhat experimental at this time, but it should be safe,
- as long as you aren't using modular USB and try to remove this
- module.
+ This is somewhat experimental at this time, but it should be safe.

+ *
+ * There are some constrains and options, to decide mapping software bits

+ * entries use the top 29 bits for TLB2.
+ *
+ * - FILE *must* be in the bottom three bits because swap cache
+ * entries use the top 29 bits for TLB2.
+ *
+ * - CACHE COHERENT bit (M) has no effect on PPC440 core, because it
+ * doesn't support SMP. So we can use this as software bit, like
+ * DIRTY.
+ *
+ * With the PPC 44x Linux implementation, the 0-11th LSBs of the PTE are used
+ * for memory protection related functions (see PTE structure in
+ * include/asm-ppc/mmu.h). The _PAGE_XXX definitions in this file map to the
+ * above bits. Note that the bit values are CPU specific, not architecture
+ * specific.
+ *
+ * The kernel PTE entry holds an arch-dependent swp_entry structure under
+ * certain situations. In other words, in such situations some portion of
+ * the PTE bits are used as a swp_entry. In the PPC implementation, the
+ * 3-24th LSB are shared with swp_entry, however the 0-2nd three LSB still
+ * hold protection values. That means the three protection bits are
+ * reserved for both PTE and SWAP entry at the most significant three
+ * LSBs.
+ *
+ * There are three protection bits available for SWAP entry:
+ * _PAGE_PRESENT
+ * _PAGE_FILE
+ * _PAGE_HASHPTE (if HW has)

+ * - If autonegotiation finishes, but there's no link, it sets
+ * the state to NOLINK.
+ * - If aneg finishes with link, it sets the state to RUNNING,

+ * - If autonegotiation did not finish after an arbitrary amount
+ * of time, autonegotiation should be tried again if the PHY
+ * supports "magic" autonegotiation (back to AN)
+ * - If it didn't finish, and no magic_aneg, move to FORCING.

+ * NOLINK: PHY is up, but not currently plugged in.
+ * - If the timer notes that the link comes back, we move to RUNNING
+ * - config_aneg moves to AN
+ * - phy_stop moves to HALTED
+ *
+ * FORCING: PHY is being configured with forced settings
+ * - if link is up, move to RUNNING
+ * - If link is down, we drop to the next highest setting, and
+ * retry (FORCING) after a timeout
+ * - phy_stop moves to HALTED
+ *
+ * RUNNING: PHY is currently up, running, and possibly sending
+ * and/or receiving packets
+ * - timer will set CHANGELINK if we're polling (this ensures the
+ * link state is polled every other cycle of this state machine,
+ * which makes it every other second)

- *
- * The interesting point, is test #2. This is what an FTP server does
- * all day. To optimize this case we use a specific flag bit defined
- * below. As we add sockets to a bind bucket list, we perform a
- * check of: (newsk->sk_reuse && (newsk->sk_state != TCP_LISTEN))
- * As long as all sockets added to a bind bucket pass this test,
- * the flag bit will be set.
- * The resulting situation is that tcp_v[46]_verify_bind() can just check
- * for this flag bit, if it is set and the socket trying to bind has
- * sk->sk_reuse set, we don't even have to walk the owners list at all,
- * we return that it is ok to bind this socket to the requested local port.
- *
- * Sounds like a lot of work, but it is worth it. In a more naive
- * implementation (ie. current FreeBSD etc.) the entire list of ports
- * must be walked for each data port opened by an ftp server. Needless
- * to say, this does not scale at all. With a couple thousand FTP
- * users logged onto your box, isn't it nice to know that new data
- * ports are created in O(1) time? I thought so. ;-) -DaveM

+ * Implements Boyer-Moore string matching algorithm:
+ *
+ * [1] A Fast String Searching Algorithm, R.S. Boyer and Moore.
+ * Communications of the Association for Computing Machinery,
+ * 20(10), 1977, pp. 762-772.

+ *
+ * [2] Handbook of Exact String Matching Algorithms, Thierry Lecroq, 2004
+ * http://www-igm.univ-mlv.fr/~lecroq/string/string.pdf
+ *
+ * Note: Since Boyer-Moore (BM) performs searches for matchings from right
+ * to left, it's still possible that a matching could be spread over
+ * multiple blocks, in that case this algorithm won't find any coincidence.
+ *
+ * If you're willing to ensure that such thing won't ever happen, use the
+ * Knuth-Pratt-Morris (KMP) implementation instead. In conclusion, choose
+ * the proper string search algorithm depending on your setting.
+ *
+ * Say you're using the textsearch infrastructure for filtering, NIDS or
+ * any similar security focused purpose, then go KMP. Otherwise, if you
+ * really care about performance, say you're classifying packets to apply
+ * Quality of Service (QoS) policies, and you don't mind about possible
+ * matchings spread over multiple fragments, then go BM.

+
+ The Datagram Congestion Control Protocol (DCCP) is a transport
+ protocol that implements bidirectional, unicast connections of
+ congestion-controlled, unreliable datagrams. It should be suitable
+ for use by applications such as streaming media, Internet telephony,
+ and on-line games
+
+ To compile this protocol support as a module, choose M here: the
+ module will be called dccp.

+ CCID 3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
+ rate-controlled congestion control mechanism. TFRC is designed to
+ be reasonably fair when competing for bandwidth with TCP-like flows,
+ where a flow is "reasonably fair" if its sending rate is generally
+ within a factor of two of the sending rate of a TCP flow under the
+ same conditions. However, TFRC has a much lower variation of
+ throughput over time compared with TCP, which makes CCID 3 more
+ suitable than CCID 2 for applications such streaming media where a
+ relatively smooth sending rate is of importance.
+
+ CCID 3 is further described in [CCID 3 PROFILE]. The TFRC
+ congestion control algorithms were initially described in RFC 3448.
+
+ This text was extracted from draft-ietf-dccp-spec-11.txt.

+/* Calculate the send rate as per section 3.1 of RFC3448
+
+Returns send rate in bytes per second
+
+Integer maths and lookups are used as not allowed floating point in kernel
+
+The function for Xcalc as per section 3.1 of RFC3448 is:
+
+X = s
+ -------------------------------------------------------------
+ R*sqrt(2*b*p/3) + (t_RTO * (3*sqrt(3*b*p/8) * p * (1+32*p^2)))
+
+where
+X is the trasmit rate in bytes/second
+s is the packet size in bytes
+R is the round trip time in seconds
+p is the loss event rate, between 0 and 1.0, of the number of loss events
+ as a fraction of the number of packets transmitted
+t_RTO is the TCP retransmission timeout value in seconds
+b is the number of packets acknowledged by a single TCP acknowledgement
+
+we can assume that b = 1 and t_RTO is 4 * R. With this the equation becomes:
+
+X = s
+ -----------------------------------------------------------------------
+ R * sqrt(2 * p / 3) + (12 * R * (sqrt(3 * p / 8) * p * (1 + 32 * p^2)))
+
+
+which we can break down into:
+
+X = s
+ --------
+ R * f(p)
+
+where f(p) = sqrt(2 * p / 3) + (12 * sqrt(3 * p / 8) * p * (1 + 32 * p * p))
+
+Function parameters:
+s - bytes
+R - RTT in usecs
+p - loss rate (decimal fraction multiplied by 1,000,000)
+
+Returns Xcalc in bytes per second

- * since a urb can handle only a single linear buffer, if the total
- * transferred area overflows the buffer boundary, we cannot send
- * it directly from the buffer. thus the data is once copied to
- * a temporary buffer and urb points to that.
+ * Since a URB can handle only a single linear buffer, we must use double
