  to Kai Groner)
* Fixed #634 problem with 'iwconfig eth1 frag 0' hanging the shell
* Fixed problem with adapter not fully powering off during suspend to RAM or
  when module unloaded.
* Improved support of iwlist freq|chan and setting of channels via iwconfig 
  to correctly check channel limits (added ieee80211_geos)
* Fixed #645 problem with turning fixed rates off not taking effect until 
  you reload the driver
* Fixed problem with firmware restart if wpa_supplicant was used to set a key
  that wasn't exactly 5 or 13 bytes in length.
* Fixed #623 Added iwpriv sw_reset extension to reset sw parameters
* Added speed_scan channel scan list support
* Added managment frame export to user space with frame statistics
* Fixed #652 Modified the driver to load the EEPROM data even if RF KILL is
  active during driver load
* Global s#CX2_#IPW_#g to make code more consistent
* Fixed #572 problem with setting txpower to auto
* Fixed #656 problem with kernel oops if mode auto; modprobe -r ipw2200
* Added QoS (CONFIG_IPW_QOS) support.  This is being actively developed but
  is the first step in getting WMM support into the driver and the kernel.
* Fixed some race conditions wich channel changes, association, and scan
  abort that could periodically cause a firmware restart.
* Misc. changes to the ieee80211 subsystem to clean up code and add additional
  support.

  (exposed through speed_scan and net_stats sysfs entries)
* Fixed #661 problem with 'pci' script (thanks to [e-mail])
* Fixed #654 problem compiling against kernel patched with SWSUSP2 (thanks to
  Henrik Brix Andersen)
* Fixed a few bugs in how monitor mode was supported (scan lists 
  weren't quite right)
* Updated the firmware requirement from 2.2 to 2.3 which supports
  monitor mode (thanks to Marek Rudniewski and Jacek Wysoczynski)


Changes in 1.0.3

* Fix #609 problem if SUSPEND2 included on kernels that do not support 
  the _BUILTIN defines.
* Fix #556 by changing 'make install' target path to /lib/modules/`uname 
  -r`/drivers/net/wireless instead of /lib/modules/`uname 
  -r`/kernel/drivers/net/wireless
* Fix #616 problem with OOPS on module load (thanks to Yi Zhu)
* Fixed problem with led module parameter being described as 
  'auto_create'
* Added support to merge between adhoc networks (thanks to Mohamed Abbas)
* Added semaphore lock at the driver's entry points to protect against 
  re-entry (thanks to Mohamed Abbas)
* Added semaphore lock to background scheduled driver actions (thanks to
  Mohamed Abbas)
* Changed how signal quality is reported for scan output (thanks to 
  Peter Jones)
* Fixed how high/low clamp values of signal quality are reported so a 
  more consistent ramp is provided (thanks to Bill Moss)
* Fix #624 problem with duplicate addresses (again)  (thanks to Bernard 
  Blackham)
* Fix #385 problem with fragmentation and certain sized packets (thanks 
  to Mohamed Abbas)
* Moved ieee80211.h and ieee80211_crypt.h into ./net so that the 
  reference to their include location does not differ from that of the 
  ieee80211 subsystem provided by netdev-2.6
* Merged latest netdev-2.6 changes to ieee80211 subsystem into driver
* Modified iwconfig network name if RF kill is enabled to say 'radio off'

  mode (thanks to Mohamed Abbas)

Changes in 1.0.2

* Removed unneeded parenthesis around numeric constant defines
* Added info about WPA to INSTALL (thanks to Henrik Brix Andersen)
* Added support for iwspy
* Put in fix for Ad-Hoc mode not passing through all packets (thanks to 
  KKH)
* Put in fix for fragmentation not working for fragment sizes between 
  441-464 bytes (thanks to Mohamed Abbas)

  spin lock protection to ieee80211's crypt handlers (thanks to Yi Zhu)
* Fixed #593 problem of CONFIG_IEEE80211_WPA_MODULE not including WPA 
  support into the driver -- fixed as a result of no longer limiting 
  WPAs inclusion
* Fixed #594 problem with user rates mask causing lack of association if 
  AP mandatory rate is masked out.  We now add back in as a supported 
  rate any mandatory rate.
* Possible fix for #597 kernel oops due to potentially calling 
  dev_kfree_skb on an skb multiple times.
* Added code to control LEDs that can be controlled through the wireless 
  NIC (vs. non-wireless HW interfaces) -- this is currently disabled by 
  default due to reports by some users of it hanging their laptop.
* Added some more debug messages around fragmentation logic
* Added locking around STATUS_HCMD_ACTIVE to prevent re-entry race 
  conditions
* Moved ipw_adapter_restart to only execute on the priv->workqueue to 
  keep keyboard errors from occuring during adapter restart
* Added CFG_BACKGROUND_SCAN to easily allow people to play with 
  background scanning implementations
* Modified WPA logic to send WPA IE if one is set (vs. being based on 
  wpa_enabled)

  based on wpa_enabled)
* Fixed issues with endianess compatability between the host and 
  wireless adapter (thanks to York Liu and Yi Zhu)
* Fixed problem with Ad-Hoc network creation causing a firmware error if 
  a scan was actively running (thanks to Mohamed Abbas)

Changes in 1.0.1

* Fixed #559: iwconfig rate support (thanks to Florian Hackenberger)
  NOTE:  Configuring a subset of rates that excludes mandatory rates by 
  your AP may result in not being able to associate with your AP.
* Improved link signal quality calculation (thanks to Bill Moss)
* Added additional debug output during scan to dump all 16 bits of 
  capability field to IEEE80211_DL_SCAN output
* Added support for additional PCI ids supported by the driver
* Removed trailing whitespace on lines in code (thanks to Henrik Brix 
  Andersen)
* Yanked script trace (-x) from helper scripts (thanks to Henrik Brix 
  Andersen)
* Fixed a problem with sensitivity threshold during association (thanks 
  to Raphael Slinckx for troubleshooting with me on IRC for three days)
* Added iwpriv for turning forcing long preamble support: 
	iwpriv eth1 set_preamble 1|0
* Possible fixes for #542 and #377 support for short preamble
* Fixed #563 compilation warning on 2.6.11-rc2 (thanks to Henrik Brix 
  Andersen)
* Fixed locked BSSID reporting channel number (thanks to Pedro Ramalhais)
* Fixed type-o with scan watchdog timeout message (thanks to Pedro Ramalhais)
* Changed logic for displaying get_mode output so the code is easier
  to follow (thanks to Pedro Ramalhais)
* Added initial support for WPA (thanks to Yi Zhu) -- tested with 
  wpa_supplicant (either tip w/ ipw driver, or with -Dipw2100) with both 
  CCMP and TKIP
* Fixed problem with CCMP not working due to uninitialized 802.11 header 
  fields (thanks to Pedro Ramalhais)
* Fixed unload script to unload the ieee80211 modules in the correct 
  order

Changes in 1.0.0

* Fixed part of #430 problem with an AP never being considered for 
  association (storming) if the jiffies rewind problem occurs (thanks to 
  Yi Zhu)

Changes in 0.22

* Changed debug log level for a fragmentation message in ieee80211 so 
  rather than use printk() it uses IEEE80211_DL_FRAG
* Fixed problem with ethtool -i not reporting the correct version string

Changes in 0.21

* Provided __iomem typedef for pre-2.6.9
* Changed firmware event/error log dumping to be masked with 
  IPW_DL_FW_ERRORS flag.  If you encounter a firmware error, your kernel 
  log will now just log the firmware restart.
* Fixed compilation warnings when CONFIG_IPW_DEBUG and 
  CONFIG_IEEE80211_DEBUG are not defined
* Fixed warning on unused return code from pci_set_consistent_dma_mask

Changes in 0.20

* Fixed #525 compilation problem with gcc 2.9.5 due to __FUNCTION__ not 
  being followed by whitespace. (thanks to Dave Hansen)
* Fixed #530 problem after any resume (thanks to Henrik Brix Andersen)
* Fixed #363 problem after S4 resume (thanks to Yi Zhu)
* Fixed #488 problem with bridged networks and Ad-Hoc by adding 
  target MAC to station table, regardless of if they are actual 
  Ad-Hoc cells (thanks to Alex Hudson)
* Fixed #221 problem with setting mode immediately after load causing 
  failures
* Incorporated fixes to use __iomem (thanks to Stephen Hemminger)
* Fixed #502 support for 64-bit platforms (thanks to Pedro Ramalhais and 
  Angelo DiNardi)
* Fixed #431 problem with pci_alloc_consistent being handed a u32 instead of 
  dma_addr_t (thanks to Jacek Wysoczynski and Marek Rudniewski)
* Fixed #379 problem w/ non-encrypted 802.1x authentication (driver no 
  longer disassociates on privacy capability change -- similar to the 
  behavior of ipw2100) 
* Fixed #509 problem w/ resetting nic possibly leaving status 
  variable bit set for a command being active.
* Fixed #450 problem w/ scan results not providing signal and level
  statistics

Changes in 0.19

NOTE: In order to upgrade to 0.19 you must also upgrade your firmware to 
2.2.  You can download the firmware from http://ipw2200.sf.net/firmware.php.

If, when loading the module, you see an error in the kernel logs about 
conflicting firmware versions, then you do not have the correct firmware 
installed.

* Fixed problem with unlocking the wrong spin lock (thanks to Yi Zhu)
* Restructured how the Link Quality is computed
* Added IPW_DEBUG_STATS for data related to how the Link Quality is computed
* Restructured how the scan channel list is constructed (cleaned up the code a 
  bit)
* Fixed #291 problem with resume not working when coming from S3 (thanks to Yi 
  Zhu)
* Fixed #489 and #387 problems with fragmentation not working
* Fixed #499 problem with packet latencies due to background scanning.  This 
  change required some logic rework in how the roaming process occurs.
* Fixed problem with some packets not being received due invalid Rx 
  filtering of BSSID
* Added SCAN watchdog to detect when scanning is not completing

Changes in 0.18

* Fixed problem with the driver thinking the privacy capability wasn't 
  matching when it was (thanks to Yi Zhu)
* Fixed #451 problem where driver wasn't reporting to user space tools when Tx
  power is disabled (radio off)
* Fixed problem with Rx queue not being protected via locks (thanks to 
  Rusty Lynch)
* Added additional debug information if an authentication failure 
  message is received.
* Fixed #492 problem with 'invalid crypt' count not being reported in 
  wireless statistics
* Fixed #495 problem with 'auto_create' module parameter not working
* Fixed #288 problem with a driver panic or system lockup during load or 
  under high load

Changes in 0.17

NOTE: In order to upgrade to 0.17 you must also upgrade your firmware to 
2.1.  You can download the firmware from http://ipw2200.sf.net/firmware.php.

If, when loading the module, you see an error in the kernel logs about 
conflicting firmware versions, then you do not have the correct firmware 
installed.

* Adjusted the behavior of ad-hoc to act much more like the ipw2100 does.
  This addresses several bugs relating to the formation/reformation of
  ad-hoc networks.
* Started initializing the ad-hoc station table when associating to an ad-hoc
  network.  This fixes a problem that is at the root of may problem reports
  where network connectivity is lost in ad-hoc mode, yet both the driver
  and networking stack configuration is correct and the device is associated
  sending out beacons.
* Added noise statistic reporting for current association
* Fixed "associate" module parameter so that it works as the README states
* Fixed signal strength reporting.  
* Added AP roaming support (via 802.11 re-association requests).  If you 
  have an ESS network that spans multiple APs and begin missing 
  enough beacons from the currently associated AP, the driver will look 
  for a better AP to associate with.  If found, it will attempt to 
  re-associate with that AP.
* Fixed code such that if a scan completes while disassociating, an 
  association attempt is not made.
* Added dumping of Status and Config during fatal error dump (to help 
  provide driver context during the fatal error)
* Changed missed beacons to report the % of missed beacons recently

Changes in 0.16

* Merged ieee80211 double alloc into single allocation (thanks to 
  Stephen Hemminger)
* Fixed compilation problem if CONFIG_IEEE80211_DEBUG is not defined 
  (thanks to Stephen Hemminger and Luc Saillard)
* Really fixed bug #271 so we properly compare essids when looking for
  a valid network to connect to
* Fixed bug #402 so that WEP can be used with ad-hoc mode
* Fixed bug #414 problem with SSIDs being scrambled when hidden networks 
  detected (also resulted in multiple hidden networks showing in scan 
  results)
* Fixed bug #425/285 problem with 802.11b networks being extremely slow
* Added support for multi-mode access points.  Fixes bugs like #397
  where the driver is not able to associate with an ap in 'b' mode 
  even though the ap provides both 'b' and 'g' bands
* Fixed bug #421 problem with a panic if fragmentation is used.  NOTE:  
  Fragmentation itself is currently broken (nothing goes through) but it 
  won't panic anymore.
* Fixed bug #237 so that link quality is now temporal and should adjust 
  dynamically as the network quality changes (previously it would slowly 
  stagnate onto a fixed level)

Changes in 0.15

* Fixed #399 - max fragmentation threshold was 2342 instead of 2346
* Fixed problem with link state no longer being detected by ethtool
* Initialize atim_window in network during scans (fixes problem with 
  adhoc networks)
