After some debuging we were hitting the following bugs so far...
* Due to huge channel list hostapd couldn't get infos from the driver and couldn't set
the channel. If we manualy set the channel after hostapd starts (by setting channel to 0 -auto),
beacons are sent but they wont show up on scan because they are malformed (they have channel = 0
because hostapd doesn't update the channel info -this is probably a hostapd bug so i'm CCing Jouni)
and they get dropped. Bob fixed this by only allowing standard channels to be registered
so now hostapd works as expected.
* Docs (and HAL source) say that we must write 0 on timer0 when operating on AP mode to start
TSF increment but this seems to mess with DBA in many cases and beacon queue never gets started.
We fixed that on the previous patch.
We have some more things to deal with...
* For some reason (hw bug or something else) after restarting hostapd a few times, beacon inteval
seems to change from 100ms to a sec (we get one beacon per sec).
* We need to set sleep timers on STA mode and enable power saving + support PCF.
...but i think it's time we enable AP support "officialy" so that we can get more feedback from
users. I ran ath5k with the mentioned patches + hostapd 0.6.8 and AP mode worked fine (it had some
less throughput on my tests than IBSS but it worked).

Should do this like:

Then git-am will pick it up automatically.
