-
-The code is based upon Ralph's test code (he did the hard stuff ;')
-
-Description
------------
-
-The 3dfx Voodoo3 chip contains two I2C interfaces (aka a I2C 'master' or
-'host').
-
-The first interface is used for DDC (Data Display Channel) which is a
-serial channel through the VGA monitor connector to a DDC-compliant
-monitor. This interface is defined by the Video Electronics Standards
-Association (VESA). The standards are available for purchase at
-http://www.vesa.org .
-
-The second interface is a general-purpose I2C bus. The intent by 3dfx was
-to allow manufacturers to add extra chips to the video card such as a
-TV-out chip such as the BT869 or possibly even I2C based temperature
-sensors like the ADM1021 or LM75.
-
-Stability
----------
-
-Seems to be stable on the test machine, but needs more testing on other
-machines. Simultaneous accesses of the DDC and I2C busses may cause errors.
-
-Supported Devices
------------------
-
-Specifically, this driver was written and tested on the '3dfx Voodoo3 AGP
-3000' which has a tv-out feature (s-video or composite). According to the
-docs and discussions, this code should work for any Voodoo3 based cards as
-well as Voodoo Banshee based cards. The DDC interface has been tested on a
-Voodoo Banshee card.
-
-Issues
-------
-
-Probably many, but it seems to work OK on my system. :')
-
-
-External Device Connection
---------------------------
-
-The digital video input jumpers give availability to the I2C bus.
-Specifically, pins 13 and 25 (bottom row middle, and bottom right-end) are
-the I2C clock and I2C data lines, respectively. +5V and GND are probably
-also easily available making the addition of extra I2C/SMBus devices easy
-to implement.

+I2C device driver binding control from user-space
+=================================================
+
+Up to kernel 2.6.32, many i2c drivers used helper macros provided by
+<linux/i2c.h> which created standard module parameters to let the user
+control how the driver would probe i2c buses and attach to devices. These
+parameters were known as "probe" (to let the driver probe for an extra
+address), "force" (to forcibly attach the driver to a given device) and
+"ignore" (to prevent a driver from probing a given address).
+
+With the conversion of the i2c subsystem to the standard device driver
+binding model, it became clear that these per-module parameters were no
+longer needed, and that a centralized implementation was possible. The new,
+sysfs-based interface is described in the documentation file
+"instantiating-devices", section "Method 4: Instantiate from user-space".
+
+Below is a mapping from the old module parameters to the new interface.
+
+Attaching a driver to an I2C device
+-----------------------------------
+
+Old method (module parameters):
+# modprobe <driver> probe=1,0x2d
+# modprobe <driver> force=1,0x2d
+# modprobe <driver> force_<device>=1,0x2d
+
+New method (sysfs interface):
+# echo <device> 0x2d > /sys/bus/i2c/devices/i2c-1/new_device
+
+Preventing a driver from attaching to an I2C device
+---------------------------------------------------
+
+Old method (module parameters):
+# modprobe <driver> ignore=1,0x2f
+
+New method (sysfs interface):
+# echo dummy 0x2f > /sys/bus/i2c/devices/i2c-1/new_device
+# modprobe <driver>
+
+Of course, it is important to instantiate the "dummy" device before loading
+the driver. The dummy device will be handled by i2c-core itself, preventing
+other drivers from binding to it later on. If there is a real device at the
+problematic address, and you want another driver to bind to it, then simply
+pass the name of the device in question instead of "dummy".

-Except for a few extremely rare exceptions user space applications do not use
-the binary sysctl interface. Instead everyone uses /proc/sys/... with
-readable ascii names.
-
-Recently the kernel has started supporting setting the binary sysctl value to
-CTL_UNNUMBERED so we no longer need to assign a binary sysctl path to allow
-sysctls to show up in /proc/sys.
-
-Assigning binary sysctl numbers is an endless source of conflicts in sysctl.h,
-breaking of the user space ABI (because of those conflicts), and maintenance
-problems. A complete pass through all of the sysctl users revealed multiple
-instances where the sysctl binary interface was broken and had gone undetected
-for years.
-
-So please do not add new binary sysctl numbers. They are unneeded and
-problematic.
-
-If you really need a new binary sysctl number please first merge your sysctl
-into the kernel and then as a separate patch allocate a binary sysctl number.

- *
- * Falcon hardware access
- *
- **************************************************************************
- *
- * Notes on locking strategy:
- *
- * Most Falcon registers require 16-byte (or 8-byte, for SRAM
- * registers) atomic writes which necessitates locking.
- * Under normal operation few writes to the Falcon BAR are made and these
- * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
- * cased to allow 4-byte (hence lockless) accesses.
- *
- * It *is* safe to write to these 4-byte registers in the middle of an
- * access to an 8-byte or 16-byte register. We therefore use a
- * spinlock to protect accesses to the larger registers, but no locks
- * for the 4-byte registers.
- *
- * A write barrier is needed to ensure that DW3 is written after DW0/1/2
- * due to the way the 16byte registers are "collected" in the Falcon BIU
- *
- * We also lock when carrying out reads, to ensure consistency of the
- * data (made possible since the BIU reads all 128 bits into a cache).
- * Reads are very rare, so this isn't a significant performance
- * impact. (Most data transferred from NIC to host is DMAed directly
- * into host memory).
- *
- * I/O BAR access uses locks for both reads and writes (but is only provided
- * for testing purposes).

+ *
+ * NIC register I/O
+ *
+ **************************************************************************
+ *
+ * Notes on locking strategy:
+ *
+ * Most NIC registers require 16-byte (or 8-byte, for SRAM) atomic writes
+ * which necessitates locking.
+ * Under normal operation few writes to NIC registers are made and these
+ * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
+ * cased to allow 4-byte (hence lockless) accesses.
+ *
+ * It *is* safe to write to these 4-byte registers in the middle of an
+ * access to an 8-byte or 16-byte register. We therefore use a
+ * spinlock to protect accesses to the larger registers, but no locks
+ * for the 4-byte registers.
+ *
+ * A write barrier is needed to ensure that DW3 is written after DW0/1/2
+ * due to the way the 16byte registers are "collected" in the BIU.
+ *
+ * We also lock when carrying out reads, to ensure consistency of the
+ * data (made possible since the BIU reads all 128 bits into a cache).
+ * Reads are very rare, so this isn't a significant performance
+ * impact. (Most data transferred from NIC to host is DMAed directly
+ * into host memory).
+ *
+ * I/O BAR access uses locks for both reads and writes (but is only provided
+ * for testing purposes).

- *

- *
- * @fn: function to run to execute work. It gets passed a 'struct
- * work_struct' that is wrapped in a 'struct i2400m_work'. Once
- * done, you have to (1) i2400m_put(i2400m_work->i2400m) and then

- *
- * @gfp_flags: GFP flags for memory allocation.
- *
- * @pl: pointer to a payload buffer that you want to pass to the _work
- * function. Use this to pack (for example) a struct with extra
- * arguments.
- *
- * @pl_size: size of the payload buffer.
- *
- * We do this quite often, so this just saves typing; allocate a
- * wrapper for a i2400m, get a ref to it, pack arguments and launch
- * the work.
- *
- * A usual workflow is:
- *
- * struct my_work_args {
- * void *something;
- * int whatever;
- * };
- * ...

- * i2400m_queue_work(i2400m, 1, my_work_function, GFP_KERNEL,
- * &args, sizeof(args))
- *
- * And now the work function can unpack the arguments and call the
- * real function (or do the job itself):
- *
- * static
- * void my_work_fn((struct work_struct *ws)
- * {
- * struct i2400m_work *iw =

- Say Y if you have a Metricom radio and intend to use Starmode Radio

- to send Internet traffic using Metricom radios. Metricom radios are
- small, battery powered, 100kbit/sec packet radio transceivers, about
- the size and weight of a cellular telephone. (You may also have heard
- them called "Metricom modems" but we avoid the term "modem" because
- it misleads many people into thinking that you can plug a Metricom
- modem into a phone line and use it as a modem.)
-
- You can use STRIP on any Linux machine with a serial port, although
- it is obviously most useful for people with laptop computers. If you
- think you might get a Metricom radio in the future, there is no harm
- in saying Y to STRIP now, except that it makes the kernel a bit
- bigger.
-
- To compile this as a module, choose M here: the module will be
- called strip.

- ---help---
- Aironet makes Arlan, a class of wireless LAN adapters. These use the
- www.Telxon.com chip, which is also used on several similar cards.
- This driver is tested on the 655 and IC2200 series cards. Look at
- <http://www.ylenurme.ee/~elmer/655/> for the latest information.
-
- The driver is built as two modules, arlan and arlan-proc. The latter
- is the /proc interface and is not needed most of time.
-
- On some computers the card ends up in non-valid state after some
- time. Use a ping-reset script to clear it.

- * ath5k_hw_set_bssid_mask - filter out bssids we listen
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode and AP mode with a single
- * BSS every bit matters since we lock to only one BSS. In AP mode with
- * multiple BSSes (virtual interfaces) not every bit matters because hw must
- * accept frames for all BSSes and so we tweak some bits of our mac address
- * in order to have multiple BSSes.
- *
- * NOTE: This is a simple filter and does *not* filter out all
- * relevant frames. Some frames that are not for us might get ACKed from us
- * by PCU because they just match the mask.
- *
- * When handling multiple BSSes you can get the BSSID mask by computing the
- * set of ~ ( MAC XOR BSSID ) for all bssids we handle.
- *
- * When you do this you are essentially computing the common bits of all your
- * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
- * the MAC address to obtain the relevant bits and compare the result with
- * (frame's BSSID & mask) to see if they match.
- */
-/*
- * Simple example: on your card you have have two BSSes you have created with
- * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
- * There is another BSSID-03 but you are not part of it. For simplicity's sake,
- * assuming only 4 bits for a mac address and for BSSIDs you can then have:
- *
- * \
- * MAC: 0001 |
- * BSSID-01: 0100 | --> Belongs to us
- * BSSID-02: 1001 |
- * /
- * -------------------
- * BSSID-03: 0110 | --> External
- * -------------------
- *
- * Our bssid_mask would then be:
- *
- * On loop iteration for BSSID-01:
- * ~(0001 ^ 0100) -> ~(0101)
- * -> 1010
- * bssid_mask = 1010
- *
- * On loop iteration for BSSID-02:
- * bssid_mask &= ~(0001 ^ 1001)
- * bssid_mask = (1010) & ~(0001 ^ 1001)
- * bssid_mask = (1010) & ~(1001)
- * bssid_mask = (1010) & (0110)
- * bssid_mask = 0010
- *
- * A bssid_mask of 0010 means "only pay attention to the second least
- * significant bit". This is because its the only bit common
- * amongst the MAC and all BSSIDs we support. To findout what the real
- * common bit is we can simply "&" the bssid_mask now with any BSSID we have
- * or our MAC address (we assume the hardware uses the MAC address).
- *
- * Now, suppose there's an incoming frame for BSSID-03:
- *
- * IFRAME-01: 0110
- *
- * An easy eye-inspeciton of this already should tell you that this frame
- * will not pass our check. This is beacuse the bssid_mask tells the
- * hardware to only look at the second least significant bit and the
- * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
- * as 1, which does not match 0.
- *
- * So with IFRAME-01 we *assume* the hardware will do:
- *
- * allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- * --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
- * --> allow = (0010) == 0000 ? 1 : 0;
- * --> allow = 0
- *
- * Lets now test a frame that should work:
- *
- * IFRAME-02: 0001 (we should allow)
- *
- * allow = (0001 & 1010) == 1010
- *
- * allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- * --> allow = (0001 & 0010) == (0010 & 0001) ? 1 :0;
- * --> allow = (0010) == (0010)
- * --> allow = 1
- *
- * Other examples:
- *
- * IFRAME-03: 0100 --> allowed
- * IFRAME-04: 1001 --> allowed
- * IFRAME-05: 1101 --> allowed but its not for us!!!

+ * @ah: atheros hardware struct
+ * @bIncTrigLevel: whether or not the frame trigger level should be updated
+ *
+ * The frame trigger level specifies the minimum number of bytes,
+ * in units of 64 bytes, that must be DMA'ed into the PCU TX FIFO
+ * before the PCU will initiate sending the frame on the air. This can
+ * mean we initiate transmit before a full frame is on the PCU TX FIFO.
+ * Resets to 0x1 (meaning 64 bytes or a full frame, whichever occurs
+ * first)
+ *
+ * Caution must be taken to ensure to set the frame trigger level based
+ * on the DMA request size. For example if the DMA request size is set to
+ * 128 bytes the trigger level cannot exceed 6 * 64 = 384. This is because
+ * there need to be enough space in the tx FIFO for the requested transfer
+ * size. Hence the tx FIFO will stop with 512 - 128 = 384 bytes. If we set
+ * the threshold to a value beyond 6, then the transmit will hang.
+ *
+ * Current dual stream devices have a PCU TX FIFO size of 8 KB.
+ * Current single stream devices have a PCU TX FIFO size of 4 KB, however,
+ * there is a hardware issue which forces us to use 2 KB instead so the
+ * frame trigger level must not exceed 2 KB for these chipsets.

+ * DOC: Programming Atheros 802.11n analog front end radios
+ *
+ * AR5416 MAC based PCI devices and AR518 MAC based PCI-Express
+ * devices have either an external AR2133 analog front end radio for single
+ * band 2.4 GHz communication or an AR5133 analog front end radio for dual
+ * band 2.4 GHz / 5 GHz communication.
+ *
+ * All devices after the AR5416 and AR5418 family starting with the AR9280
+ * have their analog front radios, MAC/BB and host PCIe/USB interface embedded
+ * into a single-chip and require less programming.
+ *
+ * The following single-chips exist with a respective embedded radio:
+ *
+ * AR9280 - 11n dual-band 2x2 MIMO for PCIe
+ * AR9281 - 11n single-band 1x2 MIMO for PCIe
+ * AR9285 - 11n single-band 1x1 for PCIe
+ * AR9287 - 11n single-band 2x2 MIMO for PCIe
+ *
+ * AR9220 - 11n dual-band 2x2 MIMO for PCI

+/**
+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ * \
+ * MAC: 0001 |
+ * BSSID-01: 0100 | --> Belongs to us
+ * BSSID-02: 1001 |
+ * /
+ * -------------------
+ * BSSID-03: 0110 | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ * On loop iteration for BSSID-01:
+ * ~(0001 ^ 0100) -> ~(0101)
+ * -> 1010
+ * bssid_mask = 1010
+ *
+ * On loop iteration for BSSID-02:
+ * bssid_mask &= ~(0001 ^ 1001)
+ * bssid_mask = (1010) & ~(0001 ^ 1001)
+ * bssid_mask = (1010) & ~(1001)
+ * bssid_mask = (1010) & (0110)
+ * bssid_mask = 0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01: 0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ * allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ * --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ * --> allow = (0010) == 0000 ? 1 : 0;
+ * --> allow = 0
+ *
+ * Lets now test a frame that should work:
+ *
+ * IFRAME-02: 0001 (we should allow)
+ *
+ * allow = (0001 & 1010) == 1010
+ *
+ * allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ * --> allow = (0001 & 0010) == (0010 & 0001) ? 1 :0;
+ * --> allow = (0010) == (0010)
+ * --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03: 0100 --> allowed
+ * IFRAME-04: 1001 --> allowed
+ * IFRAME-05: 1101 --> allowed but its not for us!!!

+IWCONFIG COMMANDS
+========================
+power period
+
+ This command is used to configure the station in deep sleep mode /
+ auto deep sleep mode.
+
+ The timer is implemented to monitor the activities (command, event,
+ etc.). When an activity is detected station will exit from deep
+ sleep mode automatically and restart the timer. At timer expiry
+ (no activity for defined time period) the deep sleep mode is entered
+ automatically.
+
+ Note: this command is for SDIO interface only.
+
+ Usage:
+ To enable deep sleep mode do:
+ iwconfig wlan0 power period 0
+ To enable auto deep sleep mode with idle time period 5 seconds do:
+ iwconfig wlan0 power period 5
+ To disable deep sleep/auto deep sleep mode do:
+ iwconfig wlan0 power period -1

+ select WIRELESS_EXT
+ ---help---
+ Aironet makes Arlan, a class of wireless LAN adapters. These use the
+ www.Telxon.com chip, which is also used on several similar cards.
+ This driver is tested on the 655 and IC2200 series cards. Look at
+ <http://www.ylenurme.ee/~elmer/655/> for the latest information.
+
+ The driver is built as two modules, arlan and arlan-proc. The latter
+ is the /proc interface and is not needed most of time.
+
+ On some computers the card ends up in non-valid state after some
+ time. Use a ping-reset script to clear it.

+ it is obviously most useful for people with laptop computers. If you
+ think you might get a Metricom radio in the future, there is no harm
+ in saying Y to STRIP now, except that it makes the kernel a bit
+ bigger.
+
+ To compile this as a module, choose M here: the module will be
+ called strip.

* stuff on the struct net without explicit struct net modification

* The rules are simple:
- * 1. register the ops with register_pernet_gen_device to get the id
- * of your private pointer;
- * 2. call net_assign_generic() to put the private data on the struct
+ * 1. set pernet_operations->id. After register_pernet_device you
+ * will have the id of your private pointer.
+ * 2. Either set pernet_operations->size (to have the code allocate and

+ * call net_assign_generic() to put the private data on the struct
* net (most preferably this should be done in the ->init callback
* of the ops registered);
* 3. do not change this pointer while the net is alive;

+ ---help---
+ IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon
+ mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly
+ deploy IPv6 unicast service to IPv4 sites to which it provides
+ customer premise equipment. Like 6to4, it utilizes stateless IPv6 in
+ IPv4 encapsulation in order to transit IPv4-only network
+ infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6
+ prefix of its own in place of the fixed 6to4 prefix.
+
+ With this option enabled, the SIT driver offers 6rd functionality by
+ providing additional ioctl API to configure the IPv6 Prefix for in
+ stead of static 2002::/16 for 6to4.
+
+ If unsure, say N.

- *
- * To fix this, we should send the frame through TX processing

- * have been software-encrypted (if applicable) already, and
- * encrypting it again doesn't do much good. So to properly do
- * that, we not only have to skip the actual 'raw' encryption
- * (key selection etc. still has to be done!) but also the
- * sequence number assignment since that impacts the crypto

- * This is actually quite unlikely even when both those events are

+ * To fix this, we should send the frame through TX processing

+ * have been software-encrypted (if applicable) already, and
+ * encrypting it again doesn't do much good. So to properly do
+ * that, we not only have to skip the actual 'raw' encryption
+ * (key selection etc. still has to be done!) but also the

-/************************** DOCUMENTATION **************************/
-/*
- * API definition :
- * --------------
- * See <linux/wireless.h> for details of the APIs and the rest.
- *
- * History :
- * -------
- *
- * v1 - 5.12.01 - Jean II
- * o Created this file.
- *
- * v2 - 13.12.01 - Jean II
- * o Move /proc/net/wireless stuff from net/core/dev.c to here
- * o Make Wireless Extension IOCTLs go through here
- * o Added iw_handler handling ;-)
- * o Added standard ioctl description
- * o Initial dumb commit strategy based on orinoco.c
- *
- * v3 - 19.12.01 - Jean II
- * o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
- * o Add event dispatcher function
- * o Add event description
- * o Propagate events as rtnetlink IFLA_WIRELESS option
- * o Generate event on selected SET requests
- *
- * v4 - 18.04.02 - Jean II
- * o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
- *
- * v5 - 21.06.02 - Jean II
- * o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
- * o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
- * o Add IWEVCUSTOM for driver specific event/scanning token
- * o Turn on WE_STRICT_WRITE by default + kernel warning
- * o Fix WE_STRICT_WRITE in ioctl_export_private() (32 => iw_num)
- * o Fix off-by-one in test (extra_size <= IFNAMSIZ)
- *
- * v6 - 9.01.03 - Jean II
- * o Add common spy support : iw_handler_set_spy(), wireless_spy_update()
- * o Add enhanced spy support : iw_handler_set_thrspy() and event.
- * o Add WIRELESS_EXT version display in /proc/net/wireless
- *
- * v6 - 18.06.04 - Jean II
- * o Change get_spydata() method for added safety
- * o Remove spy #ifdef, they are always on -> cleaner code
- * o Allow any size GET request if user specifies length > max
- * and if request has IW_DESCR_FLAG_NOMAX flag or is SIOCGIWPRIV
- * o Start migrating get_wireless_stats to struct iw_handler_def
- * o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
- * Based on patch from Pavel Roskin <proski@gnu.org> :
- * o Fix kernel data leak to user space in private handler handling
- *
- * v7 - 18.3.05 - Jean II
- * o Remove (struct iw_point *)->pointer from events and streams
- * o Remove spy_offset from struct iw_handler_def
- * o Start deprecating dev->get_wireless_stats, output a warning
- * o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
- * o Don't lose INVALID/DBM flags when clearing UPDATED flags (iwstats)
- *
- * v8 - 17.02.06 - Jean II
- * o RtNetlink requests support (SET/GET)
- *
- * v8b - 03.08.06 - Herbert Xu
- * o Fix Wireless Event locking issues.
- *
- * v9 - 14.3.06 - Jean II
- * o Change length in ESSID and NICK to strlen() instead of strlen()+1
- * o Make standard_ioctl_num and standard_event_num unsigned
- * o Remove (struct net_device *)->get_wireless_stats()
- *
- * v10 - 16.3.07 - Jean II
- * o Prevent leaking of kernel space in stream on 64 bits.

+ firmware files called "scope.cod" and "sndscape.co?" where the
+ ? is digit 0, 1, 2, 3 or 4. The firmware files can be found
+ in DOS or Windows driver packages. One has to put the firmware
+ files into the /lib/firmware directory.
To compile this driver as a module, choose M here: the module
will be called snd-sscape.
