My real goal is to support lots (128+ hopefully) of
virtual stations on ath5k and ath9k.  We had this working
for ath5k in .31 kernel, but too much has changed to make it
a straight-forward upgrade to .34.

As soon as I can get the management logic fixed up (ie, libnl
to listen to wireless events, etc), we should be able to start
on the virtualization work in earnest.

Thanks,
Ben
