Changes in 1.0.7

NOTE:  In order to upgrade to 1.0.7, you must:

   http://ieee80211.sf.net
2. Obtain the latest firmware (v2.4) from 
   http://ipw2200.sf.net/firmware.php

* Fix problem with 'Driver using old /proc/net/wireless' message (thanks 
  to Benoit Boissinot)
* Fixed #771 problem with too many (8) bytes being received when using 
  AES/hwcrypto.

  not set.

  enabled (resolving a firmware restart)
* Fixed support of mixed PTK/GTK CCMP/TKIP support
* Fixed is_network_packet to check for broadcast packets
* Modified all places where firmware loading can fail to report 
  the errno in decimal format for easy tracking (thanks to Peter 
  Jones)
* Fixed 760 problem with setting WEP key in monitor mode causes IV loss 
  and decrypt attempt on captured packets.
* Fixed 455 problem with frequent channel changes causing a firmware 
  error.
* Updated copyright strings
* Modified firmware error and event log capturing to capture into 
  allocated data blocks vs. pulling from registers.
* Changed ipw_dump_nic_error_log to ipw_dump_error_log and adjusted to 
  use pre-allocated log blocks.
* Added wait_state wakeup on scan completion.
* Added event_log and error_log sysfs entries.
* Modified all ipw_send_cmd() usage to report errors within ipw_send_cmd 
  vs. within each of the callers.  This allows uniform error returns as 
  well as uniform debug logging.
* Modified ipw_config and STATUS_INIT setting to correct race 
  condition with request_scan being called before initialized if invoked 
  from insmod, resulting in no association occurring during boot until 
  iwlist scan is run.
* Updated version stamp for firmware from 2.3 to 2.4.
* Fix firmware error when setting tx_power.
* Fixed #751 Fix driver association requires manual scan.

* Fixed #701 Fix a misuse of ieee->mode with ieee->iw_mode.
* Fixed the ad-hoc network WEP key list issue.
* Fixed #792 Fix WPA-PSK AES both for -Dipw and -Dwext.
* Disable host fragmentation in open mode since IPW2200/2915 hardware
  support hardware fragmentation.
* Workaround kernel BUG_ON panic caused by unexpected duplicate packets.
* Added more useful geography encoding so people's experience with
  iwconfig matches what their hardware can actually do in regard to
  supported channel maps, etc.
* Misc. updates to be in sync w/ latest ieee80211 subsystem
	- Use of ieee80211_hdr to ieee80211_hdr_Naddr
	- Added is_queue_full for 802.11e support.
	- Added handle_probe_response, handle_beacon, 
          handle_association_response callbacks.
* Changed default # of missed beacons to miss before disassociation 
  to 24 (vs. 9 which is too low in most environments)
* [unstable] Added command log sysfs entry for recording firmware 
  interactions even in non-debug builds
* Radiotap type frames support for monitor mode, which requires Libpcap 
  0.9.3+ to parse correctly in the user space (thanks to Mike Kershaw 
  for the radiotap addition, and Stefan Rompf who provided an initial 
  implementation for adding AVS which then motivated the radiotap work.)
* Fixed #801 problem with intermittent firmware restarts in weak signal 
  areas due to roaming logic
* Fixed some compiler issues if CONFIG_IPW2200_QOS is enabled.
