In monitor mode, the card receives frames fine. But when trying to associate, the card hangs.

TODO (for a reminder for me):

* try a different slot
* try without an AR9280 in the other slot
* try creating an adhoc AP and TX'ing unicast/broadcast packets w/ another laptop in monitor mode to see if it makes it out into the air

Also:

* try a HAL checkout from -before- my changes. I seem to recall test this a while ago and I found that it worked (well enough.)
* Try a HAL checkout from my GIT HAL, see if that works too.

>How-To-Repeat:
Configure it up in station mode; attach wpa_supplicant; attempt to associate to a 11bg AP.
