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.
