9-stable with -head ath/net80211 stacks

[Johann Hugo]

Hi

Got 11n up and running in hostap mode on 9-stable with -head ath/net80211 
stacks. Unfortunately I only have one 802.11n adapter to play with. 

The only 11n client I could find was my Samsung Galaxy S2 and it works very 
well.

The only problem that I got so far is that 11n only works if I don't set the 
country or regdomain.

AP-vlan:~ # ifconfig wlan0
wlan0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu

If I change the country to ZA then it defaults to 11a

If I change it back to country US then it also defaults to 11a, but the 
regdomain also changes to FCC
