Subject: [PATCH 10/10] wifi: remove ipw2100/ipw2200 drivers
From: Arnd Bergmann <arnd@...db.de>
These two drivers were used for the earliest "Centrino" branded Intel
laptops during the late 32-bit Pentium-M era, roughly 2003 to 2005, which
probably makes it the most modern platform that still uses the wireless
extension interface instead of cfg80211. Unlike the other drivers that
are suggested for removal, this one is still officially maintained.
According to Johannes Berg, there was an effort to finish the move away
from wext in the past, but the last evidence of this that I could find
is from commit a3caa99e6c68f ("libipw: initiate cfg80211 API conversion
(v2)") in 2009.

-
-Intel wireless LAN adapters are engineered, manufactured, tested, and
-quality checked to ensure that they meet all necessary local and
-governmental regulatory agency requirements for the regions that they
-are designated and/or marked to ship into. Since wireless LANs are
-generally unlicensed devices that share spectrum with radars,
-satellites, and other licensed and unlicensed devices, it is sometimes
-necessary to dynamically detect, avoid, and limit usage to avoid
-interference with these devices. In many instances Intel is required to
-provide test data to prove regional and local compliance to regional and
-governmental regulations before certification or approval to use the
-product is granted. Intel's wireless LAN's EEPROM, firmware, and
-software driver are designed to carefully control parameters that affect
-radio operation and to ensure electromagnetic compliance (EMC). These
-parameters include, without limitation, RF power, spectrum usage,
-channel scanning, and human exposure.
-
-For these reasons Intel cannot permit any manipulation by third parties
-of the software provided in binary format with the wireless WLAN
-adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
-patches, utilities, or code with the Intel wireless LAN adapters that
-have been manipulated by an unauthorized party (i.e., patches,
-utilities, or code (including open source code modifications) which have
-not been validated by Intel), (i) you will be solely responsible for
-ensuring the regulatory compliance of the products, (ii) Intel will bear
-no liability, under any theory of liability for any issues associated
-with the modified products, including without limitation, claims under
-the warranty and/or issues arising from regulatory non-compliance, and
-(iii) Intel will not provide or be required to assist in providing
-support to any third parties for such modified products.
-
-Note: Many regulatory agencies consider Wireless LAN adapters to be
-modules, and accordingly, condition system-level regulatory approval
-upon receipt and review of test data documenting that the antennas and
-system configuration do not cause the EMC and radio operation to be
-non-compliant.
-
-The drivers available for download from SourceForge are provided as a
-part of a development project. Conformance to local regulatory
-requirements is the responsibility of the individual developer. As
-such, if you are interested in deploying or shipping a driver as part of
-solution intended to be used for purposes other than development, please
-obtain a tested driver from Intel Customer Support at:
-
-https://www.intel.com/support/wireless/sb/CS-006408.htm
-
-1. Introduction
-===============
-
-This document provides a brief overview of the features supported by the
-IPW2100 driver project. The main project website, where the latest
-development version of the driver can be found, is:
-
- http://ipw2100.sourceforge.net
-
-There you can find the not only the latest releases, but also information about
-potential fixes and patches, as well as links to the development mailing list
-for the driver project.
-
-
-2. Release git-1.1.5 Current Supported Features
-===============================================
-
-- Managed (BSS) and Ad-Hoc (IBSS)
-- WEP (shared key and open)
-- Wireless Tools support
-- 802.1x (tested with XSupplicant 1.0.1)
-
-Enabled (but not supported) features:
-- Monitor/RFMon mode
-- WPA/WPA2
-
-The distinction between officially supported and enabled is a reflection
-on the amount of validation and interoperability testing that has been
-performed on a given feature.
-
-
-3. Command Line Parameters
-==========================
-
-If the driver is built as a module, the following optional parameters are used
-by entering them on the command line with the modprobe command using this
-syntax::
-
- modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
-
-For example, to disable the radio on driver loading, enter:
-
- modprobe ipw2100 disable=1
-
-The ipw2100 driver supports the following module parameters:
-
-========= ============== ============ ==============================
-Name Value Example Meaning
-========= ============== ============ ==============================
-debug 0x0-0xffffffff debug=1024 Debug level set to 1024
-mode 0,1,2 mode=1 AdHoc
-channel int channel=3 Only valid in AdHoc or Monitor
-associate boolean associate=0 Do NOT auto associate
-disable boolean disable=1 Do not power the HW
-========= ============== ============ ==============================
-
-
-4. Sysfs Helper Files
-=====================
-
-There are several ways to control the behavior of the driver. Many of the
-general capabilities are exposed through the Wireless Tools (iwconfig). There
-are a few capabilities that are exposed through entries in the Linux Sysfs.
-
-
-**Driver Level**
-
-For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
-
- debug_level
- This controls the same global as the 'debug' module parameter. For
- information on the various debugging levels available, run the 'dvals'
- script found in the driver source directory.
-
- .. note::
-
- 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn on.
-
-**Device Level**
-
-For the device level files look in::
-
- /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
-
-For example::
-
- /sys/bus/pci/drivers/ipw2100/0000:02:01.0
-
-For the device level files, see /sys/bus/pci/drivers/ipw2100:
-
- rf_kill
- read
-
- == =========================================
- 0 RF kill not enabled (radio on)
- 1 SW based RF kill active (radio off)
- 2 HW based RF kill active (radio off)
- 3 Both HW and SW RF kill active (radio off)
- == =========================================
-
- write
-
- == ==================================================
- 0 If SW based RF kill active, turn the radio back on
- 1 If radio is on, activate SW based RF kill
- == ==================================================
-
- .. note::
-
- If you enable the SW based RF kill and then toggle the HW
- based RF kill from ON -> OFF -> ON, the radio will NOT come back on
-
-
-5. Radio Kill Switch
-====================
-
-Most laptops provide the ability for the user to physically disable the radio.
-Some vendors have implemented this as a physical switch that requires no
-software to turn the radio off and on. On other laptops, however, the switch
-is controlled through a button being pressed and a software driver then making
-calls to turn the radio off and on. This is referred to as a "software based
-RF kill switch"
-
-See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
-on your system.
-
-
-6. Dynamic Firmware
-===================
-
-As the firmware is licensed under a restricted use license, it can not be
-included within the kernel sources. To enable the IPW2100 you will need a
-firmware image to load into the wireless NIC's processors.
-
-You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
-
-See INSTALL for instructions on installing the firmware.
-
-
-7. Power Management
-===================
-
-The IPW2100 supports the configuration of the Power Save Protocol
-through a private wireless extension interface. The IPW2100 supports
-the following different modes:
-
- === ===========================================================
- off No power management. Radio is always on.
- on Automatic power management
- 1-5 Different levels of power management. The higher the
- number the greater the power savings, but with an impact to
- packet latencies.
- === ===========================================================
-
-Power management works by powering down the radio after a certain
-interval of time has passed where no packets are passed through the
-radio. Once powered down, the radio remains in that state for a given
-period of time. For higher power savings, the interval between last
-packet processed to sleep is shorter and the sleep period is longer.
-
-When the radio is asleep, the access point sending data to the station
-must buffer packets at the AP until the station wakes up and requests
-any buffered packets. If you have an AP that does not correctly support
-the PSP protocol you may experience packet loss or very poor performance
-while power management is enabled. If this is the case, you will need
-to try and find a firmware update for your AP, or disable power
-management (via ``iwconfig eth1 power off``)
-
-To configure the power level on the IPW2100 you use a combination of
-iwconfig and iwpriv. iwconfig is used to turn power management on, off,
-and set it to auto.
-
- ========================= ====================================
- iwconfig eth1 power off Disables radio power down
- iwconfig eth1 power on Enables radio power management to
- last set level (defaults to AUTO)
- iwpriv eth1 set_power 0 Sets power level to AUTO and enables
- power management if not previously
- enabled.
- iwpriv eth1 set_power 1-5 Set the power level as specified,
- enabling power management if not
- previously enabled.
- ========================= ====================================
-
-You can view the current power level setting via::
-
- iwpriv eth1 get_power
-
-It will return the current period or timeout that is configured as a string
-in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
-time after packet processing), yyyy is the period to sleep (amount of time to
-wait before powering the radio and querying the access point for buffered
-packets), and z is the 'power level'. If power management is turned off the
-xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
-level if `iwconfig eth1 power on` is invoked.

-1. Introduction
-===============
-
-The following sections attempt to provide a brief introduction to using
-the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
-
-This document is not meant to be a comprehensive manual on
-understanding or using wireless technologies, but should be sufficient
-to get you moving without wires on Linux.
-
-For information on building and installing the driver, see the INSTALL
-file.
-
-
-1.1. Overview of Features
--------------------------
-The current release (1.1.2) supports the following features:
-
-+ BSS mode (Infrastructure, Managed)
-+ IBSS mode (Ad-Hoc)
-+ WEP (OPEN and SHARED KEY mode)
-+ 802.1x EAP via wpa_supplicant and xsupplicant
-+ Wireless Extension support
-+ Full B and G rate support (2200 and 2915)
-+ Full A rate support (2915 only)
-+ Transmit power control
-+ S state support (ACPI suspend/resume)
-
-The following features are currently enabled, but not officially
-supported:
-
-+ WPA
-+ long/short preamble support
-+ Monitor mode (aka RFMon)
-
-The distinction between officially supported and enabled is a reflection
-on the amount of validation and interoperability testing that has been
-performed on a given feature.
-
-
-
-1.2. Command Line Parameters
-----------------------------
-
-Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
-2915ABG Driver for Linux allows configuration options to be provided
-as module parameters. The most common way to specify a module parameter
-is via the command line.
-
-The general form is::
-
- % modprobe ipw2200 parameter=value
-
-Where the supported parameter are:
-
- associate
- Set to 0 to disable the auto scan-and-associate functionality of the
- driver. If disabled, the driver will not attempt to scan
- for and associate to a network until it has been configured with
- one or more properties for the target network, for example configuring
- the network SSID. Default is 0 (do not auto-associate)
-
- Example: % modprobe ipw2200 associate=0
-
- auto_create
- Set to 0 to disable the auto creation of an Ad-Hoc network
- matching the channel and network name parameters provided.
- Default is 1.
-
- channel
- channel number for association. The normal method for setting
- the channel would be to use the standard wireless tools
- (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
- to set this while debugging. Channel 0 means 'ANY'
-
- debug
- If using a debug build, this is used to control the amount of debug
- info is logged. See the 'dvals' and 'load' script for more info on
- how to use this (the dvals and load scripts are provided as part
- of the ipw2200 development snapshot releases available from the
- SourceForge project at http://ipw2200.sf.net)
-
- led
- Can be used to turn on experimental LED code.
- 0 = Off, 1 = On. Default is 1.
-
- mode
- Can be used to set the default mode of the adapter.
- 0 = Managed, 1 = Ad-Hoc, 2 = Monitor
-
-
-1.3. Wireless Extension Private Methods
----------------------------------------
-
-As an interface designed to handle generic hardware, there are certain
-capabilities not exposed through the normal Wireless Tool interface. As
-such, a provision is provided for a driver to declare custom, or
-private, methods. The Intel(R) PRO/Wireless 2915ABG Driver for Linux
-defines several of these to configure various settings.
-
-The general form of using the private wireless methods is::
-
- % iwpriv $IFNAME method parameters
-
-Where $IFNAME is the interface name the device is registered with
-(typically eth1, customized via one of the various network interface
-name managers, such as ifrename)
-
-The supported private methods are:
-
- get_mode
- Can be used to report out which IEEE mode the driver is
- configured to support. Example:
-
- % iwpriv eth1 get_mode
- eth1 get_mode:802.11bg (6)
-
- set_mode
- Can be used to configure which IEEE mode the driver will
- support.
-
- Usage::
-
- % iwpriv eth1 set_mode {mode}
-
- Where {mode} is a number in the range 1-7:

-1.4. Sysfs Helper Files
------------------------
-
-The Linux kernel provides a pseudo file system that can be used to
-access various components of the operating system. The Intel(R)
-PRO/Wireless 2915ABG Driver for Linux exposes several configuration
-parameters through this mechanism.
-
-An entry in the sysfs can support reading and/or writing. You can
-typically query the contents of a sysfs entry through the use of cat,
-and can set the contents via echo. For example::
-
- % cat /sys/bus/pci/drivers/ipw2200/debug_level
-
-Will report the current debug level of the driver's logging subsystem
-(only available if CONFIG_IPW2200_DEBUG was configured when the driver
-was built).
-
-You can set the debug level via::
-
- % echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
-
-Where $VALUE would be a number in the case of this sysfs entry. The
-input to sysfs files does not have to be a number. For example, the
-firmware loader used by hotplug utilizes sysfs entries for transferring
-the firmware image from user space into the driver.
-
-The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
-at two levels -- driver level, which apply to all instances of the driver
-(in the event that there are more than one device installed) and device
-level, which applies only to the single specific instance.
-
-
-1.4.1 Driver Level Sysfs Helper Files
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
-
- debug_level
- This controls the same global as the 'debug' module parameter
-
-
-
-1.4.2 Device Level Sysfs Helper Files
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-For the device level files, look in::
-
- /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
-
-For example:::
-
- /sys/bus/pci/drivers/ipw2200/0000:02:01.0
-
-For the device level files, see /sys/bus/pci/drivers/ipw2200:

-
-1.5. Supported channels
------------------------
-
-Upon loading the Intel(R) PRO/Wireless 2915ABG Driver for Linux, a
-message stating the detected geography code and the number of 802.11
-channels supported by the card will be displayed in the log.
-
-The geography code corresponds to a regulatory domain as shown in the
-table below.
-

-2. Ad-Hoc Networking
-=====================
-
-When using a device in an Ad-Hoc network, it is useful to understand the
-sequence and requirements for the driver to be able to create, join, or
-merge networks.
-
-The following attempts to provide enough information so that you can
-have a consistent experience while using the driver as a member of an
-Ad-Hoc network.
-
-2.1. Joining an Ad-Hoc Network
-------------------------------
-
-The easiest way to get onto an Ad-Hoc network is to join one that
-already exists.
-
-2.2. Creating an Ad-Hoc Network
--------------------------------
-
-An Ad-Hoc networks is created using the syntax of the Wireless tool.
-
-For Example:
-iwconfig eth1 mode ad-hoc essid testing channel 2
-
-2.3. Merging Ad-Hoc Networks
-----------------------------
-
-
-3. Interaction with Wireless Tools
-==================================
-
-3.1 iwconfig mode
------------------
-
-When configuring the mode of the adapter, all run-time configured parameters
-are reset to the value used when the module was loaded. This includes
-channels, rates, ESSID, etc.
-
-3.2 iwconfig sens
------------------
-
-The 'iwconfig ethX sens XX' command will not set the signal sensitivity
-threshold, as described in iwconfig documentation, but rather the number
-of consecutive missed beacons that will trigger handover, i.e. roaming
-to another access point. At the same time, it will set the disassociation
-threshold to 3 times the given value.
-
-
-4. About the Version Numbers
-=============================
-
-Due to the nature of open source development projects, there are
-frequently changes being incorporated that have not gone through
-a complete validation process. These changes are incorporated into
-development snapshot releases.
-
-Releases are numbered with a three level scheme:
-
- major.minor.development
-
-Any version where the 'development' portion is 0 (for example
-1.0.0, 1.1.0, etc.) indicates a stable version that will be made
-available for kernel inclusion.
-
-Any version where the 'development' portion is not a 0 (for
-example 1.0.1, 1.1.5, etc.) indicates a development version that is
-being made available for testing and cutting edge users. The stability
-and functionality of the development releases are not know. We make
-efforts to try and keep all snapshots reasonably stable, but due to the
-frequency of their release, and the desire to get those releases
-available as quickly as possible, unknown anomalies should be expected.
-
-The major version number will be incremented when significant changes
-are made to the driver. Currently, there are no major changes planned.
-
-5. Firmware installation
-========================
-
-The driver requires a firmware image, download it and extract the
-files under /lib/firmware (or wherever your hotplug's firmware.agent
-will look for firmware files)
-
-The firmware can be downloaded from the following URL:
-
- http://ipw2200.sf.net/
-
-
-6. Support

-
- Initial driver on which this is based was developed by Janusz Gorycki,
- Maciej Urbaniak, and Maciej Sosnowski.
-
- Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
-
-Theory of Operation
-
-Tx - Commands and Data
-
-Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
-Each TBD contains a pointer to the physical (dma_addr_t) address of data being
-sent to the firmware as well as the length of the data.
-
-The host writes to the TBD queue at the WRITE index. The WRITE index points
-to the _next_ packet to be written and is advanced when after the TBD has been
-filled.
-
-The firmware pulls from the TBD queue at the READ index. The READ index points
-to the currently being read entry, and is advanced once the firmware is
-done with a packet.
-
-When data is sent to the firmware, the first TBD is used to indicate to the
-firmware if a Command or Data is being sent. If it is Command, all of the
-command information is contained within the physical address referred to by the
-TBD. If it is Data, the first TBD indicates the type of data packet, number
-of fragments, etc. The next TBD then refers to the actual packet location.
-
-The Tx flow cycle is as follows:
-
-1) ipw2100_tx() is called by kernel with SKB to transmit
-2) Packet is move from the tx_free_list and appended to the transmit pending
- list (tx_pend_list)
-3) work is scheduled to move pending packets into the shared circular queue.
-4) when placing packet in the circular queue, the incoming SKB is DMA mapped
- to a physical address. That address is entered into a TBD. Two TBDs are
- filled out. The first indicating a data packet, the second referring to the
- actual payload data.
-5) the packet is removed from tx_pend_list and placed on the end of the
- firmware pending list (fw_pend_list)
-6) firmware is notified that the WRITE index has
-7) Once the firmware has processed the TBD, INTA is triggered.
-8) For each Tx interrupt received from the firmware, the READ index is checked
- to see which TBDs are done being processed.
-9) For each TBD that has been processed, the ISR pulls the oldest packet
- from the fw_pend_list.
-10)The packet structure contained in the fw_pend_list is then used
- to unmap the DMA address and to free the SKB originally passed to the driver
- from the kernel.
-11)The packet structure is placed onto the tx_free_list
-
-The above steps are the same for commands, only the msg_free_list/msg_pend_list
-are used instead of tx_free_list/tx_pend_list
-
-...
-
-Critical Sections / Locking :
-
-There are two locks utilized. The first is the low level lock (priv->low_lock)
-that protects the following:
-
-- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
-
- tx_free_list : Holds pre-allocated Tx buffers.
- TAIL modified in __ipw2100_tx_process()
- HEAD modified in ipw2100_tx()

- tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
- TAIL modified ipw2100_tx()
- HEAD modified by ipw2100_tx_send_data()
-
- msg_free_list : Holds pre-allocated Msg (Command) buffers
- TAIL modified in __ipw2100_tx_process()

- msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
- TAIL modified in ipw2100_hw_send_command()
- HEAD modified in ipw2100_tx_send_commands()
-
- The flow of data on the TX side is as follows:
-
- MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
- TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
-
- The methods that work on the TBD ring are protected via priv->low_lock.
-
-- The internal data state of the device itself
-- Access to the firmware read/write indexes for the BD queues
- and associated logic
-
-All external entry functions are locked with the priv->action_lock to ensure
-that only one external action is invoked at a time.

- * Rx theory of operation
- *
- * The host allocates 32 DMA target addresses and passes the host address
- * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
- * 0 to 31
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer it will advance the READ index
- * and fire the RX interrupt. The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
- * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- * to replensish the ipw->rxq->rx_free.
- * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
- * ipw->rxq is replenished and the READ INDEX is updated (updating the
- * 'processed' and 'read' driver indexes as well)
- * + A received packet is processed and handed to the kernel network stack,
- * detached from the ipw->rxq. The driver 'processed' index is updated.
- * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
- * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
- * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
- * were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * ipw_rx_queue_alloc() Allocates rx_free
- * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
- * ipw_rx_queue_restock
- * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
- * queue, updates firmware pointers, and updates
- * the WRITE index. If insufficient rx_free buffers
- * are available, schedules ipw_rx_queue_replenish
- *
- * -- enable interrupts --
- * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
- * READ INDEX, detaching the SKB from the pool.
- * Moves the packet buffer from queue to rx_used.
- * Calls ipw_rx_queue_restock to refill any empty
- * slots.
- * ...

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts. The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames. With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.
