WPA branch merged into HEAD

I've just completed the back mege of the WPA branch into HEAD. The WPA branch should be considered dead and as soon as the public CVS is updated you should start pulling code from HEAD.

For those that have not been following the WPA branch note that the directory organization has changed. The old driver and wlan directories are replaced by ath and net80211, respectively. If you use

cvs up -dP

the old directories should be pruned so things will be less confusing. The version strings on the updated code should be 0.9.3.0 for the ath driver and 0.8.3.0 for the net80211 module. The module names have not changed.
