- BCM43xx Linux Driver Project
- ============================
-
-Introduction
-------------
-
-Many of the wireless devices found in modern notebook computers are
-based on the wireless chips produced by Broadcom. These devices have
-been a problem for Linux users as there is no open-source driver
-available. In addition, Broadcom has not released specifications
-for the device, and driver availability has been limited to the
-binary-only form used in the GPL versions of AP hardware such as the
-Linksys WRT54G, and the Windows and OS X drivers. Before this project
-began, the only way to use these devices were to use the Windows or
-OS X drivers with either the Linuxant or ndiswrapper modules. There
-is a strong penalty if this method is used as loading the binary-only
-module "taints" the kernel, and no kernel developer will help diagnose
-any kernel problems.
-
-Development
------------
-
-This driver has been developed using
-a clean-room technique that is described at
-http://bcm-specs.sipsolutions.net/ReverseEngineeringProcess. For legal
-reasons, none of the clean-room crew works on the on the Linux driver,
-and none of the Linux developers sees anything but the specifications,
-which are the ultimate product of the reverse-engineering group.
-
-Software
---------
-
-Since the release of the 2.6.17 kernel, the bcm43xx driver has been
-distributed with the kernel source, and is prebuilt in most, if not
-all, distributions. There is, however, additional software that is
-required. The firmware used by the chip is the intellectual property
-of Broadcom and they have not given the bcm43xx team redistribution
-rights to this firmware. Since we cannot legally redistribute
-the firmware we cannot include it with the driver. Furthermore, it
-cannot be placed in the downloadable archives of any distributing
-organization; therefore, the user is responsible for obtaining the
-firmware and placing it in the appropriate location so that the driver
-can find it when initializing.
-
-To help with this process, the bcm43xx developers provide a separate
-program named bcm43xx-fwcutter to "cut" the firmware out of a
-Windows or OS X driver and write the extracted files to the proper
-location. This program is usually provided with the distribution;
-however, it may be downloaded from
-
-http://developer.berlios.de/project/showfiles.php?group_id=4547
-
-The firmware is available in two versions. V3 firmware is used with
-the in-kernel bcm43xx driver that uses a software MAC layer called
-SoftMAC, and will have a microcode revision of 0x127 or smaller. The
-V4 firmware is used by an out-of-kernel driver employing a variation of
-the Devicescape MAC layer known as d80211. Once bcm43xx-d80211 reaches
-a satisfactory level of development, it will replace bcm43xx-softmac
-in the kernel as it is much more flexible and powerful.
-
-A source for the latest V3 firmware is
-
-http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
-
-Once this file is downloaded, the command
-'bcm43xx-fwcutter -w <dir> <filename>'
-will extract the microcode and write it to directory
-<dir>. The correct directory will depend on your distribution;
-however, most use '/lib/firmware'. Once this step is completed,
-the bcm3xx driver should load when the system is booted. To see
-any messages relating to the driver, issue the command 'dmesg |
-grep bcm43xx' from a terminal window. If there are any problems,
-please send that output to Bcm43xx-dev@lists.berlios.de.
-
-Although the driver has been in-kernel since 2.6.17, the earliest
-version is quite limited in its capability. Patches that include
-all features of later versions are available for the stable kernel
-versions from 2.6.18. These will be needed if you use a BCM4318,
-or a PCI Express version (BCM4311 and BCM4312). In addition, if you
-have an early BCM4306 and more than 1 GB RAM, your kernel will need
-to be patched. These patches, which are being updated regularly,
-are available at ftp://lwfinger.dynalias.org/patches. Look for
-combined_2.6.YY.patch. Of course you will need kernel source downloaded
-from kernel.org, or the source from your distribution.
-
-If you build your own kernel, please enable CONFIG_BCM43XX_DEBUG
-and CONFIG_IEEE80211_SOFTMAC_DEBUG. The log information provided is
-essential for solving any problems.

-Linux WAN Router Utilities Package
-------------------------------------------------------------------------------
-Version 2.2.1
-Mar 28, 2001
-Author: Nenad Corbic <ncorbic@sangoma.com>

-INTRODUCTION
-
-Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs)
-and/or stand-alone hosts over vast distances with data transfer rates
-significantly higher than those achievable with commonly used dial-up
-connections.
-
-Usually an external device called `WAN router' sitting on your local network
-or connected to your machine's serial port provides physical connection to
-WAN. Although router's job may be as simple as taking your local network
-traffic, converting it to WAN format and piping it through the WAN link, these
-devices are notoriously expensive, with prices as much as 2 - 5 times higher
-then the price of a typical PC box.
-
-Alternatively, considering robustness and multitasking capabilities of Linux,
-an internal router can be built (most routers use some sort of stripped down
-Unix-like operating system anyway). With a number of relatively inexpensive WAN
-interface cards available on the market, a perfectly usable router can be
-built for less than half a price of an external router. Yet a Linux box
-acting as a router can still be used for other purposes, such as fire-walling,
-running FTP, WWW or DNS server, etc.
-
-This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux
-operating system and provides generic hardware-independent services for such
-drivers. Why can existing Linux network device interface not be used for
-this purpose? Well, it can. However, there are a few key differences between
-a typical network interface (e.g. Ethernet) and a WAN link.
-
-Many WAN protocols, such as X.25 and frame relay, allow for multiple logical
-connections (known as `virtual circuits' in X.25 terminology) over a single
-physical link. Each such virtual circuit may (and almost always does) lead
-to a different geographical location and, therefore, different network. As a
-result, it is the virtual circuit, not the physical link, that represents a
-route and, therefore, a network interface in Linux terms.
-
-To further complicate things, virtual circuits are usually volatile in nature
-(excluding so called `permanent' virtual circuits or PVCs). With almost no
-time required to set up and tear down a virtual circuit, it is highly desirable
-to implement on-demand connections in order to minimize network charges. So
-unlike a typical network driver, the WAN driver must be able to handle multiple
-network interfaces and cope as multiple virtual circuits come into existence
-and go away dynamically.
-
-Last, but not least, WAN configuration is much more complex than that of say
-Ethernet and may well amount to several dozens of parameters. Some of them
-are "link-wide" while others are virtual circuit-specific. The same holds
-true for WAN statistics which is by far more extensive and extremely useful
-when troubleshooting WAN connections. Extending the ifconfig utility to suit
-these needs may be possible, but does not seem quite reasonable. Therefore, a
-WAN configuration utility and corresponding application programmer's interface
-is needed for this purpose.
-
-Most of these problems are taken care of by this module. Its goal is to
-provide a user with more-or-less standard look and feel for all WAN devices and
-assist a WAN device driver writer by providing common services, such as:
-
- o User-level interface via /proc file system
- o Centralized configuration
- o Device management (setup, shutdown, etc.)
- o Network interface management (dynamic creation/destruction)

-ACKNOWLEDGEMENTS
-
-This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
-by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x. Success of the WANPIPE
-together with the next major release of Linux kernel in summer 1996 commanded
-adequate changes to the WANPIPE code to take full advantage of new Linux
-features.
-
-Instead of continuing developing proprietary interface tied to Sangoma WAN
-cards, we decided to separate all hardware-independent code into a separate
-module and defined two levels of interfaces - one for user-level applications
-and another for kernel-level WAN drivers. WANPIPE is now implemented as a
-WAN driver compliant with the WAN Link Driver interface. Also a general
-purpose WAN configuration utility and a set of shell scripts was developed to
-support WAN router at the user level.
-
-Many useful ideas concerning hardware-independent interface implementation
-were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
-of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).
-
-With the new implementation of the APIs being incorporated into the WANPIPE,
-a special thank goes to Alan Cox in providing insight into BSD sockets.
-
-Special thanks to all the WANPIPE users who performed field-testing, reported
-bugs and made valuable comments and suggestions that help us to improve this
-product.
-
-
-
-NEW IN THIS RELEASE
-
- o Updated the WANCFG utility
- Calls the pppconfig to configure the PPPD
- for async connections.
-
- o Added the PPPCONFIG utility
- Used to configure the PPPD daemon for the
- WANPIPE Async PPP and standard serial port.
- The wancfg calls the pppconfig to configure
- the pppd.
-
- o Fixed the PCI autodetect feature.
- The SLOT 0 was used as an autodetect option
- however, some high end PC's slot numbers start
- from 0.
-
- o This release has been tested with the new backupd
- daemon release.

- o cfgft1 GUI csu/dsu configurator
- o wancfg GUI configuration file
- configurator.
- o Architectural directory changes.
-
-beta-2.1.4 Jul 2000 o Dynamic interface configuration:
- Network interfaces reflect the state
- of protocol layer. If the protocol becomes
- disconnected, driver will bring down
- the interface. Once the protocol reconnects
- the interface will be brought up.
-
- Note: This option is turned off by default.
-
- o Dynamic wanrouter setup using 'wanconfig':
- wanconfig utility can be used to
- shutdown,restart,start or reconfigure
- a virtual circuit dynamically.
-
- Frame Relay: Each DLCI can be:
- created,stopped,restarted and reconfigured
- dynamically using wanconfig.
-
- ex: wanconfig card wanpipe1 dev wp1_fr16 up
-
- o Wanrouter startup via command line arguments:
- wanconfig also supports wanrouter startup via command line
- arguments. Thus, there is no need to create a wanpipe#.conf
- configuration file.
-
- o Socket based x25api update/bug fixes.
- Added support for LCN numbers greater than 255.
- Option to pass up modem messages.
- Provided a PCI IRQ check, so a single S514
- card is guaranteed to have a non-sharing interrupt.
-
- o Fixes to the wancfg utility.
- o New FT1 debugging support via *pipemon utilities.
- o Frame Relay ARP support Enabled.
-
-beta3-2.1.4 Jul 2000 o X25 M_BIT Problem fix.
- o Added the Multi-Port PPP
- Updated utilities for the Multi-Port PPP.
-
-2.1.4 Aut 2000
- o In X25API:
- Maximum packet an application can send
- to the driver has been extended to 4096 bytes.
-
- Fixed the x25 startup bug. Enable
- communications only after all interfaces
- come up. HIGH SVC/PVC is used to calculate
- the number of channels.
- Enable protocol only after all interfaces
- are enabled.
-
- o Added an extra state to the FT1 config, kernel module.
- o Updated the pipemon debuggers.
-
- o Blocked the Multi-Port PPP from running on kernels
- 2.2.16 or greater, due to syncppp kernel module
- change.
-
-beta1-2.1.5 Nov 15 2000
- o Fixed the MultiPort PPP Support for kernels 2.2.16 and above.
- 2.2.X kernels only
-
- o Secured the driver UDP debugging calls
- - All illegal network debugging calls are reported to
- the log.
- - Defined a set of allowed commands, all other denied.
-
- o Cpipemon
- - Added set FT1 commands to the cpipemon. Thus CSU/DSU
- configuration can be performed using cpipemon.
- All systems that cannot run cfgft1 GUI utility should
- use cpipemon to configure the on board CSU/DSU.
-
-
- o Keyboard Led Monitor/Debugger
- - A new utility /usr/sbin/wpkbdmon uses keyboard leds
- to convey operational statistic information of the
- Sangoma WANPIPE cards.
- NUM_LOCK = Line State (On=connected, Off=disconnected)
- CAPS_LOCK = Tx data (On=transmitting, Off=no tx data)
- SCROLL_LOCK = Rx data (On=receiving, Off=no rx data
-
- o Hardware probe on module load and dynamic device allocation
- - During WANPIPE module load, all Sangoma cards are probed
- and found information is printed in the /var/log/messages.
- - If no cards are found, the module load fails.
- - Appropriate number of devices are dynamically loaded
- based on the number of Sangoma cards found.
-
- Note: The kernel configuration option
- CONFIG_WANPIPE_CARDS has been taken out.
-
- o Fixed the Frame Relay and Chdlc network interfaces so they are
- compatible with libpcap libraries. Meaning, tcpdump, snort,
- ethereal, and all other packet sniffers and debuggers work on
- all WANPIPE network interfaces.
- - Set the network interface encoding type to ARPHRD_PPP.
- This tell the sniffers that data obtained from the
- network interface is in pure IP format.
- Fix for 2.2.X kernels only.
-
- o True interface encoding option for Frame Relay and CHDLC
- - The above fix sets the network interface encoding
- type to ARPHRD_PPP, however some customers use
- the encoding interface type to determine the
- protocol running. Therefore, the TURE ENCODING
- option will set the interface type back to the
- original value.
-
- NOTE: If this option is used with Frame Relay and CHDLC
- libpcap library support will be broken.
- i.e. tcpdump will not work.
- Fix for 2.2.x Kernels only.
-
- o Ethernet Bridgind over Frame Relay
- - The Frame Relay bridging has been developed by
- Kristian Hoffmann and Mark Wells.
- - The Linux kernel bridge is used to send ethernet
- data over the frame relay links.
- For 2.2.X Kernels only.
-
- o Added extensive 2.0.X support. Most new features of
- 2.1.5 for protocols Frame Relay, PPP and CHDLC are
- supported under 2.0.X kernels.
-
-beta1-2.2.0 Dec 30 2000
- o Updated drivers for 2.4.X kernels.
- o Updated drivers for SMP support.
- o X25API is now able to share PCI interrupts.
- o Took out a general polling routine that was used
- only by X25API.
- o Added appropriate locks to the dynamic reconfiguration
- code.
- o Fixed a bug in the keyboard debug monitor.
-
-beta2-2.2.0 Jan 8 2001
- o Patches for 2.4.0 kernel
- o Patches for 2.2.18 kernel
- o Minor updates to PPP and CHLDC drivers.
- Note: No functional difference.
-
-beta3-2.2.9 Jan 10 2001
- o I missed the 2.2.18 kernel patches in beta2-2.2.0
- release. They are included in this release.
-
-Stable Release
-2.2.0 Feb 01 2001
- o Bug fix in wancfg GUI configurator.
- The edit function didn't work properly.
-
-
-bata1-2.2.1 Feb 09 2001
- o WANPIPE TTY Driver emulation.
- Two modes of operation Sync and Async.
- Sync: Using the PPPD daemon, kernel SyncPPP layer
- and the Wanpipe sync TTY driver: a PPP protocol
- connection can be established via Sangoma adapter, over
- a T1 leased line.
-
- The 2.4.0 kernel PPP layer supports MULTILINK
- protocol, that can be used to bundle any number of Sangoma
- adapters (T1 lines) into one, under a single IP address.
- Thus, efficiently obtaining multiple T1 throughput.
-
- NOTE: The remote side must also implement MULTILINK PPP
- protocol.
-
- Async:Using the PPPD daemon, kernel AsyncPPP layer
- and the WANPIPE async TTY driver: a PPP protocol
- connection can be established via Sangoma adapter and
- a modem, over a telephone line.
-
- Thus, the WANPIPE async TTY driver simulates a serial
- TTY driver that would normally be used to interface the
- MODEM to the linux kernel.
-
- o WANPIPE PPP Backup Utility
- This utility will monitor the state of the PPP T1 line.
- In case of failure, a dial up connection will be established
- via pppd daemon, ether via a serial tty driver (serial port),
- or a WANPIPE async TTY driver (in case serial port is unavailable).
-
- Furthermore, while in dial up mode, the primary PPP T1 link
- will be monitored for signs of life.
-
- If the PPP T1 link comes back to life, the dial up connection
- will be shutdown and T1 line re-established.
-
-
- o New Setup installation script.
- Option to UPGRADE device drivers if the kernel source has
- already been patched with WANPIPE.
-
- Option to COMPILE WANPIPE modules against the currently
- running kernel, thus no need for manual kernel and module
- re-compilation.
-
- o Updates and Bug Fixes to wancfg utility.
-
-bata2-2.2.1 Feb 20 2001
-
- o Bug fixes to the CHDLC device drivers.
- The driver had compilation problems under kernels
- 2.2.14 or lower.
-
- o Bug fixes to the Setup installation script.
- The device drivers compilation options didn't work
- properly.
-
- o Update to the wpbackupd daemon.
- Optimized the cross-over times, between the primary
- link and the backup dialup.
-
-beta3-2.2.1 Mar 02 2001
- o Patches for 2.4.2 kernel.
-
- o Bug fixes to util/ make files.
- o Bug fixes to the Setup installation script.
-
- o Took out the backupd support and made it into
- as separate package.
-
-beta4-2.2.1 Mar 12 2001
-
- o Fix to the Frame Relay Device driver.
- IPSAC sends a packet of zero length
- header to the frame relay driver. The
- driver tries to push its own 2 byte header
- into the packet, which causes the driver to
- crash.
-
- o Fix the WANPIPE re-configuration code.
- Bug was found by trying to run the cfgft1 while the
- interface was already running.
-
- o Updates to cfgft1.
- Writes a wanpipe#.cfgft1 configuration file
- once the CSU/DSU is configured. This file can
- holds the current CSU/DSU configuration.

- Say Y here if you have a Marvell Yukon or SysKonnect SK-98xx/SK-95xx
- compliant Gigabit Ethernet Adapter.
-
- This driver supports the original Yukon chipset. This driver is
- deprecated and will be removed from the kernel in the near future,
- it has been replaced by the skge driver. skge is cleaner and
- seems to work better.
-
- This driver does not support the newer Yukon2 chipset. A separate
- driver, sky2, is provided to support Yukon2-based adapters.
-
- The following adapters are supported by this driver:
- - 3Com 3C940 Gigabit LOM Ethernet Adapter
- - 3Com 3C941 Gigabit LOM Ethernet Adapter
- - Allied Telesyn AT-2970LX Gigabit Ethernet Adapter

- Questions concerning this driver may be addressed to:
- <linux@syskonnect.de>
-
- If you want to compile this driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/kbuild/modules.txt>. The module will
- be called sk98lin. This is recommended.

- * Add more ethtool functions.
- * Fix abstruse irq enable/disable condition described here:

- *
- * NEEDS TESTING:

- * Description:
- *
- * This is the main module of the Linux GE driver.
- *
- * All source files except skge.c, skdrv1st.h, skdrv2nd.h and sktypes.h
- * are part of SysKonnect's COMMON MODULES for the SK-98xx adapters.
- * Those are used for drivers on multiple OS', so some thing may seem
- * unnecessary complicated on Linux. Please do not try to 'clean up'
- * them without VERY good reasons, because this will make it more
- * difficult to keep the Linux driver in synchronisation with the
- * other versions.
- *
- * Include file hierarchy:
- *
- * <linux/module.h>
- *
- * "h/skdrv1st.h"
- * <linux/types.h>
- * <linux/kernel.h>
- * <linux/string.h>

- * <asm/byteorder.h>
- * <asm/io.h>
- * <linux/netdevice.h>
- * <linux/etherdevice.h>
- * <linux/skbuff.h>
- * those three depending on kernel version used:
- * <linux/bios32.h>

- * Description:
- * After calling this function the descriptor rings and Rx and Tx
- * queues of this port may be reconfigured.
- *
- * It is possible to stop the receive and transmit path separate or
- * both together.
- *
- * Dir = SK_STOP_TX Stops the transmit path only and resets the MAC.
- * The receive queue is still active and
- * the pending Rx frames may be still transferred
- * into the RxD.
- * SK_STOP_RX Stop the receive path. The tansmit path
- * has to be stopped once before.
- * SK_STOP_ALL SK_STOP_TX + SK_STOP_RX
- *
- * RstMode = SK_SOFT_RST Resets the MAC. The PHY is still alive.
- * SK_HARD_RST Resets the MAC and the PHY.
- *
- * Example:
- * 1) A Link Down event was signaled for a port. Therefore the activity
- * of this port should be stopped and a hardware reset should be issued
- * to enable the workaround of XMAC Errata #2. But the received frames
- * should not be discarded.

- * (transfer all pending Rx frames)
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_RX, SK_HARD_RST);
- * ...
- *
- * 2) An event was issued which request the driver to switch
- * the 'virtual active' link to an other already active port
- * as soon as possible. The frames in the receive queue of this
- * port may be lost. But the PHY must not be reset during this
- * event.
- * ...
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_ALL, SK_SOFT_RST);
- * ...
- *
- * Extended Description:
- * If SK_STOP_TX is set,
- * o disable the MAC's receive and transmitter to prevent
- * from sending incomplete frames
- * o stop the port's transmit queues before terminating the
- * BMUs to prevent from performing incomplete PCI cycles
- * on the PCI bus
- * - The network Rx and Tx activity and PCI Tx transfer is
- * disabled now.
- * o reset the MAC depending on the RstMode
- * o Stop Interval Timer and Limit Counter of Tx Arbiter,
- * also disable Force Sync bit and Enable Alloc bit.
- * o perform a local reset of the port's Tx path
- * - reset the PCI FIFO of the async Tx queue
- * - reset the PCI FIFO of the sync Tx queue
- * - reset the RAM Buffer async Tx queue
- * - reset the RAM Buffer sync Tx queue
- * - reset the MAC Tx FIFO
- * o switch Link and Tx LED off, stop the LED counters
- *
- * If SK_STOP_RX is set,
- * o stop the port's receive queue
- * - The path data transfer activity is fully stopped now.
- * o perform a local reset of the port's Rx path
- * - reset the PCI FIFO of the Rx queue
- * - reset the RAM Buffer receive queue
- * - reset the MAC Rx FIFO
- * o switch Rx LED off, stop the LED counter
- *
- * If all ports are stopped,

- * SK_PNMI_EVT_XMAC_RESET The event is generated by the driver

- * Special Interrupt handler
- *
- * The following abstract should show how this module is included
- * in the driver path:
- *
- * In the ISR of the driver the bits for frame transmission complete and
- * for receive complete are checked and handled by the driver itself.
- * The bits of the slow path mask are checked after that and then the
- * entry into the so-called "slow path" is prepared. It is an implementors
- * decision whether this is executed directly or just scheduled by
- * disabling the mask. In the interrupt service routine some events may be
- * generated, so it would be a good idea to call the EventDispatcher
- * right after this ISR.
- *
- * The Interrupt source register of the adapter is NOT read by this module.
- * SO if the drivers implementor needs a while loop around the
- * slow data paths interrupt bits, he needs to call the SkGeSirqIsr() for
- * each loop entered.
- *
- * However, the MAC Interrupt status registers are read in a while loop.

- I2C protocol implementation.
-
- General Description:
-
- The I2C protocol is used for the temperature sensors and for
- the serial EEPROM which hold the configuration.
-
- This file covers functions that allow to read write and do
- some bulk requests a specified I2C address.
-
- The Genesis has 2 I2C buses. One for the EEPROM which holds
- the VPD Data and one for temperature and voltage sensor.
- The following picture shows the I2C buses, I2C devices and
- their control registers.
-
- Note: The VPD functions are in skvpd.c
-.

-. | B2_I2C | | B2_I2C | | B2_I2C |
-. | _CTRL | | _DATA | | _SW |
-. +--------+ +--------+ +----------+
-.
- The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL
- and B2_I2C_DATA registers.
- For driver software it is recommended to use the I2C control and
- data register, because I2C bus timing is done by the ASIC and
- an interrupt may be received when the I2C request is completed.
-
- Clock Rate Timing: MIN MAX generated by
- VPD EEPROM: 50 kHz 100 kHz HW
- LM80 over I2C Ctrl/Data reg. 50 kHz 100 kHz HW
- LM80 over B2_I2C_SW register 0 400 kHz SW
-
- Note: The clock generated by the hardware is dependend on the
- PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD
- clock is 50 kHz.

-/* Auto negotiation. The scheme is very simple. We have a timer routine
- * that keeps watching the auto negotiation process as it progresses.
- * The DP83840 is first told to start doing it's thing, we set up the time
- * and place the timer state machine in it's initial state.
- *
- * Here the timer peeks at the DP83840 status registers at each click to see
- * if the auto negotiation has completed, we assume here that the DP83840 PHY
- * will time out at some point and just tell us what (didn't) happen. For
- * complete coverage we only allow so many of the ticks at this level to run,
- * when this has expired we print a warning message and try another strategy.
- * This "other" strategy is to force the interface into various speed/duplex
- * configurations and we stop when we see a link-up condition before the
- * maximum number of "peek" ticks have occurred.
- *
- * Once a valid link status has been detected we configure the BigMAC and
- * the rest of the Happy Meal to speak the most efficient protocol we could
- * get a clean link for. The priority for link configurations, highest first
- * is:
- * 100 Base-T Full Duplex
- * 100 Base-T Half Duplex
- * 10 Base-T Full Duplex
- * 10 Base-T Half Duplex
- *
- * We start a new timer now, after a successful auto negotiation status has
- * been detected. This timer just waits for the link-up bit to get set in
- * the BMCR of the DP83840. When this occurs we print a kernel log message
- * describing the link type in use and the fact that it is up.
- *
- * If a fatal error of some sort is signalled and detected in the interrupt
- * service routine, and the chip is reset, or the link is ifconfig'd down
- * and then back up, this entire process repeats itself all over again.

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver was forked from the driver for the DECchip "Tulip",
-Digital's single-chip ethernet controllers for PCI. It supports Xircom's
-almost-Tulip-compatible CBE-100 CardBus adapters.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS preferably should assign the
-PCI INTA signal to an otherwise unused system IRQ line.
-
-III. Driver operation
-
-IIIa. Ring buffers
-
-The Xircom can use either ring buffers or lists of Tx and Rx descriptors.
-This driver uses statically allocated rings of Rx and Tx descriptors, set at
-compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs
-for the Rx ring buffers at open() time and passes the skb->data field to the
-Xircom as receive data buffers. When an incoming frame is less than
-RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is
-copied to the new skbuff. When the incoming frame is larger, the skbuff is
-passed directly up the protocol stack and replaced by a newly allocated
-skbuff.
-
-The RX_COPYBREAK value is chosen to trade-off the memory wasted by
-using a full-sized skbuff for small frames vs. the copying costs of larger
-frames. For small frames the copying cost is negligible (esp. considering
-that we are pre-loading the cache with immediately useful header
-information). For large frames the copying cost is non-trivial, and the
-larger copy might flush the cache of useful data. A subtle aspect of this
-choice is that the Xircom only receives into longword aligned buffers, thus
-the IP header at offset 14 isn't longword aligned for further processing.
-Copied frames are put into the new skbuff at an offset of "+2", thus copying
-has the beneficial effect of aligning the IP header and preloading the
-cache.
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control. One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag. The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-The send packet thread has partial control over the Tx ring and 'dev->tbusy'
-flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next
-queue slot is empty, it clears the tbusy flag when finished otherwise it sets
-the 'tp->tx_full' flag.
-
-The interrupt handler has exclusive control over the Rx ring and records stats
-from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so
-we can't avoid the interrupt overhead by having the Tx routine reap the Tx
-stats.) After reaping the stats, it marks the queue entry as empty by setting
-the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the
-tx_full and tbusy flags.

- * To quote Arjan van de Ven:

- * it's called voodoo as I stole this code and cannot cross-reference
- * it with the specification.
- * Actually it seems to go like this:
- * - GPIO2 enables the MII itself so we can talk to it. The MII gets reset
- * so any prior MII settings are lost.
- * - GPIO0 enables the TP port so the MII can talk to the network.
- * - a software reset will reset both GPIO pins.
- * I also moved the software reset here, because doing it in xircom_up()
- * required enabling the GPIO pins each time, which reset the MII each time.
- * Thus we couldn't control the MII -- which sucks because we don't know
- * how to handle full-duplex modes so we *must* disable them.

+ This module adds support for wireless adapters based on
+ Atheros 5xxx chipset.
+
+ Currently the following chip versions are supported:
+
+ MAC: AR5211 AR5212
+ PHY: RF5111/2111 RF5112/2112 RF5413/2413
+
+ This driver uses the kernel's mac80211 subsystem.
+
+ If you choose to build a module, it'll be called ath5k. Say M if
+ unsure.
+
+config ATH5K_DEBUG
+ bool "Atheros 5xxx debugging"
+ depends on ATH5K
+ ---help---
+ Atheros 5xxx debugging messages.
+
+ Say Y, if and you will get debug options for ath5k.
+ To use this, you need to mount debugfs:
+
+ mkdir /debug/
+ mount -t debugfs debug /debug/
+
+ You will get access to files under:
+ /debug/ath5k/phy0/
+
+ To enable debug, pass the debug level to the debug module
+ parameter. For example:
+
+ modprobe ath5k debug=0x00000400

- * IO, register, and NIC memory access functions
- *
- * NOTE on naming convention and macro usage for these
- *
- * A single _ prefix before a an access function means that no state
- * check or debug information is printed when that function is called.
- *
- * A double __ prefix before an access function means that state is checked
- * and the current line number is printed in addition to any other debug output.
- *
- * The non-prefixed name is the #define that maps the caller into a
- * #define that provides the caller's __LINE__ to the double prefix version.
- *
- * If you wish to call the function without any debug or state checking,
- * you should use the single _ prefix version (as is used by dependent IO
- * routines, for example _iwl4965_read_direct32 calls the non-check version of
- * _iwl4965_read32.)
- *
- * These declarations are *extremely* useful in quickly isolating code deltas
- * which result in misconfiguring of the hardware I/O. In combination with
- * git-bisect and the IO debug level you can quickly determine the specific
- * commit which breaks the IO sequence to the hardware.

+ * up after power-saving sleeps (or during initial uCode load), the BSM loads
+ * the bootstrap program into the on-board processor, and starts it.
+ *
+ * The bootstrap program loads (via DMA) instructions and data for a new
+ * program from host DRAM locations indicated by the host driver in the
+ * BSM_DRAM_* registers. Once the new program is loaded, it starts
+ * automatically.
+ *
+ * When initializing the NIC, the host driver points the BSM to the
+ * "initialize" uCode image. This uCode sets up some internal data, then
+ * notifies host via "initialize alive" that it is complete.
+ *
+ * The host then replaces the BSM_DRAM_* pointer values to point to the
+ * normal runtime uCode instructions and a backup uCode data cache buffer
+ * (filled initially with starting data values for the on-board processor),
+ * then triggers the "initialize" uCode to load and launch the runtime uCode,
+ * which begins normal operation.
+ *
+ * When doing a power-save shutdown, runtime uCode saves data SRAM into
+ * the backup data cache in DRAM before SRAM is powered down.
+ *
+ * When powering back up, the BSM loads the bootstrap program. This reloads
+ * the runtime uCode instructions and the backup data cache into SRAM,
+ * and re-launches the runtime uCode from where it left off.

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel. We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware. This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel. There is no corresponding channel information for that
+ * entry.

-/************************** EEPROM BANDS ****************************
- *
- * The iwl4965_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl4965_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel. We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware. This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel. There is no corresponding channel information for that
- * entry.

- *
- * BSM operation:
- *
- * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
- * in special SRAM that does not power down during RFKILL. When powering back
- * up after power-saving sleeps (or during initial uCode load), the BSM loads
- * the bootstrap program into the on-board processor, and starts it.
- *
- * The bootstrap program loads (via DMA) instructions and data for a new
- * program from host DRAM locations indicated by the host driver in the
- * BSM_DRAM_* registers. Once the new program is loaded, it starts
- * automatically.
- *
- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image. This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program. This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,
- * and re-launches the runtime uCode from where it left off.

These are the protocols used on the Internet and on most local
Ethernets. It is highly recommended to say Y here (this will enlarge
- your kernel by about 144 KB), since some programs (e.g. the X window
+ your kernel by about 400 KB), since some programs (e.g. the X window
system) use TCP/IP even if your machine is not connected to any
other computer. You will get the so-called loopback device which
allows you to ping yourself (great fun, that!).

- * This regulatory domain control implementation is known to be incomplete

- * reworked in the not-too-distant future.
- *
- * For now, drivers wishing to control which channels are and aren't available
- * are advised as follows:
- * - set the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag
- * - continue to include *ALL* possible channels in the modes registered
- * through ieee80211_register_hwmode()
- * - for each allowable ieee80211_channel structure registered in the above
- * call, set the flag member to some meaningful value such as
- * IEEE80211_CHAN_W_SCAN | IEEE80211_CHAN_W_ACTIVE_SCAN |
- * IEEE80211_CHAN_W_IBSS.
- * - leave flag as 0 for non-allowable channels
- *
- * The usual implementation is for a driver to read a device EEPROM to
- * determine which regulatory domain it should be operating under, then
- * looking up the allowable channels in a driver-local table, then performing
- * the above.

+ * RCU, i.e. access to the list and hash table is protected by RCU.
+ *
+ * Upon allocating a STA info structure with sta_info_alloc(), the caller owns
+ * that structure. It must then either destroy it using sta_info_destroy()
+ * (which is pretty useless) or insert it into the hash table using
+ * sta_info_insert() which demotes the reference from ownership to a regular
+ * RCU-protected reference; if the function is called without protection by an
+ * RCU critical section the reference is instantly invalidated. Note that the
+ * caller may not do much with the STA info before inserting it, in particular,
+ * it may not start any mesh peer link management or add encryption keys.
+ *
+ * When the insertion fails (sta_info_insert()) returns non-zero), the
+ * structure will have been freed by sta_info_insert()!
+ *
+ * Because there are debugfs entries for each station, and adding those
+ * must be able to sleep, it is also possible to "pin" a station entry,
+ * that means it can be removed from the hash table but not be freed.
+ * See the comment in __sta_info_unlink() for more information, this is
+ * an internal capability only.
+ *
+ * In order to remove a STA info structure, the caller needs to first
+ * unlink it (sta_info_unlink()) from the list and hash tables and
+ * then destroy it; sta_info_destroy() will wait for an RCU grace period
+ * to elapse before actually freeing it. Due to the pinning and the
+ * possibility of multiple callers trying to remove the same STA info at
+ * the same time, sta_info_unlink() can clear the STA info pointer it is
+ * passed to indicate that the STA info is owned by somebody else now.
+ *
+ * If sta_info_unlink() did not clear the pointer then the caller owns
+ * the STA info structure now and is responsible of destroying it with
+ * a call to sta_info_destroy().
+ *
+ * In all other cases, there is no concept of ownership on a STA entry,
+ * each structure is owned by the global hash table/list until it is
+ * removed. All users of the structure need to be RCU protected so that
+ * the structure won't be freed before they are done using it.

- * not be used here, since the same lock must protect ports
- * with non-socket interfaces.
- * See net.c for description of locking policy.
+ * Revised TIPC socket locking policy:
+ *
+ * Most socket operations take the standard socket lock when they start
+ * and hold it until they finish (or until they need to sleep). Acquiring
+ * this lock grants the owner exclusive access to the fields of the socket
+ * data structures, with the exception of the backlog queue. A few socket
+ * operations can be done without taking the socket lock because they only
+ * read socket information that never changes during the life of the socket.
+ *
+ * Socket operations may acquire the lock for the associated TIPC port if they
+ * need to perform an operation on the port. If any routine needs to acquire
+ * both the socket lock and the port lock it must take the socket lock first
+ * to avoid the risk of deadlock.
+ *
+ * The dispatcher handling incoming messages cannot grab the socket lock in
+ * the standard fashion, since invoked it runs at the BH level and cannot block.
+ * Instead, it checks to see if the socket lock is currently owned by someone,
+ * and either handles the message itself or adds it to the socket's backlog
+ * queue; in the latter case the queued message is processed once the process
+ * owning the socket lock releases it.
+ *
+ * NOTE: Releasing the socket lock while an operation is sleeping overcomes
+ * the problem of a blocked socket operation preventing any other operations
+ * from occurring. However, applications must be careful if they have
+ * multiple threads trying to send (or receive) on the same socket, as these
+ * operations might interfere with each other. For example, doing a connect
+ * and a receive at the same time might allow the receive to consume the
+ * ACK message meant for the connect. While additional work could be done
+ * to try and overcome this, it doesn't seem to be worthwhile at the present.
+ *
+ * NOTE: Releasing the socket lock while an operation is sleeping also ensures
+ * that another operation that must be performed in a non-blocking manner is
+ * not delayed for very long because the lock has already been taken.
+ *
+ * NOTE: This code assumes that certain fields of a port/socket pair are
+ * constant over its lifetime; such fields can be examined without taking
+ * the socket lock and/or port lock, and do not need to be re-read even
+ * after resuming processing after waiting. These fields include:
+ * - socket type
+ * - pointer to socket sk structure (aka tipc_sock structure)
+ * - pointer to port structure
+ * - port reference
