Thanks for the contribution.  Sending packets in monitor mode is a
mistake; you should use adhoc demo mode.  Future versions of the hal are
likely to disallow packet transmission.

I've had changes to send 802.11 frames via bpf for a long time (12+
months).  They go through the net80211 layer and are device independent.
 I'll try to clean 'em up so you can try them.
