+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

+ *

+ * 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.

+ *   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
