I tested bwn injection in ahdemo long ago (and bwn have not changed at
all from that time on CURRENT).

There is one caveat with bwn driver:

The interface (wlan0 from bwn0) must be set to UP with ifconfig.
Setting it with aireplay/airodump may result in kernel panic but
usually you will just get blank output from aireplay/airodump.
