+===========================
+0. 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.
+
+
+===========================
+1. Release 1.1.0 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.
+
+
+===========================
+2. 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:
+debug 0x0-0xffffffff debug=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 */
+
+
+===========================
+3. 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
+
+
+===========================
+4. 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.
+
+
+===========================
+5. 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.
+
+
+===========================
+6. 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 (1.0.0) 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)
++ long/short preamble support
+
+
+
+1.2. Command Line Parameters
+-----------------------------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
+2915ABG Driver for Linux allows certain 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 1 (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 'dval' and 'load' script for more info on
+ how to use this (the dval and load scripts are provided as part
+ of the ipw2200 development snapshot releases available from the
+ SourceForge project at http://ipw2200.sf.net)
+
+ mode
+ Can be used to set the default mode of the adapter.
+ 0 = Managed, 1 = Ad-Hoc
+
+
+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:
+ 1 802.11a (2915 only)
+ 2 802.11b
+ 3 802.11ab (2915 only)
+ 4 802.11g
+ 5 802.11ag (2915 only)
+ 6 802.11bg
+ 7 802.11abg (2915 only)
+
+ get_preamble
+ Can be used to report configuration of preamble length.
+
+ set_preamble
+ Can be used to set the configuration of preamble length:
+
+ Usage:
+ % iwpriv eth1 set_preamble {mode}
+ Where {mode} is one of:
+ 1 Long preamble only
+ 0 Auto (long or short based on connection)
+
+
+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_IPW_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:
+
+ 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
+
+ ucode
+ read-only access to the ucode version number
+
+
+2. 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.
+
+
