if_bwn woes

[Eitan Adler]

On a fresh 8.1-RELEASE install

ifconfig wlan0 scan results in no output and takes forever (ie - it hangs)
ifconfig wlan0 ssid my_ssid
dhclient wlan0
results in no link being discovered

Here is some relevant system config and such to help diagnose the problem:

#ifconfig wlan0 create wlandev bwn0

#ifconfig bwn0
bwn0: flags=8843<UP,BROADCAST,RUNNIN,SIMPLEX,MULTICAST> metric 0 mtu 2290
   ether xx:yy:zz:xx:yy:zz
