+
+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.
+
+
+3.  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 referrs 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 X__ipw2100_tx_send_data()
+
+  msg_free_list : Holds pre-allocated Msg (Command) buffers
+    TAIL modified in __ipw2100_tx_process()
+    HEAD modified in ipw2100_hw_send_command()
+
+  msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
+    TAIL modified in ipw2100_hw_send_command()
+    HEAD modified in X__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 CX2_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

+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.
