That description could use some work :)

It's not quite clear to me why this needs new API, and new semantics
for the existing AUTH/ASSOC commands. In fact, the latter I dislike
most, because those commands/events are only used in client mode right
now, and having them in AP mode now seems confusing.

Perhaps just mirroring the frames to userspace with CMD_FRAME, if
needed with a new flag that they're already handled or so would be
better?
