Testing 802.11n

[Warren Block]

-CURRENT plus yesterday's patch.  The kernel config is just

   include GENERIC
   nocpu   I486_CPU
   ident   TEST11N

   option  ATH_ENABLE_11N

ifconfig wlan0 shows

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

Should this work?

# ifconfig wlan0 mode 11n
ifconfig: SIOCSIFMEDIA (media): Device not configured
