The problem is caused by the patch in bug455 -- Channel change flood
generates fatal error.

The patch set the DISASSOCIATING status bit after sending the command.
The process was scheduled out when waiting for the command to be sent to
the card. The disassociated notification clears the DISASSOCIATING bit
in the tasklet before the process set the bit.

Move the bit setting code before sending the command now.

Because of the frequent channel change, it is possible that when we are
try to associate with channel 1 (authenticated but not associated).
Another channel change comes at this time, then the driver will issue
disassociate command to the firmware which will cause the fatal error.

It seems that the association/disassociation procedure should not be
interrupted.

The patch attached adds test on STATUS_ASSOCIATING | STATUS_DISASSOCIATING
in ipw_send_cmd(), when ensures that commands will not be sent to firmware
when we are in these two status.

We send SYSTEM_CONFIG command after the TGI_KEY command if hardware
encryption is enabled. It sometimes causes a firmware stall (firmware
doesn't respond to any request) and finally bungs up the Tx send queue.
The solution is to send SYSTEM_CONFIG command in the post association
stage from a workqueue.

Removed unneeded parenthesis around numeric constant defines

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)

Fixed #592 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

any mandatory rate.

Fixed #597 kernel oops due to 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)

Modified scan result logic to report WPA and RSN IEs if set (vs. being
