I gave this a decent try a month or two ago, and had no luck.  The hardware
(from what I can tell), just will not send a frame to an unknown peer.

I noticed the other day that ANQP will not work on ath10k, and I suspect
similar issues..so I will be in that code again.  Maybe I'll learn
how to trick it into sending arbitrary frames.

All that said, there is no way to specify rate-ctrl info on a per-pkt
basis when injecting frames, so I don't know what good injecting frames
on a mgt device will accomplish.

Thanks,
Ben
