This would require some tricks:
 - monitor vdev can't tx so you'll need other vdev type allocated side-by-sdie
 - tx often may require peer entries (see offchan code in mac.c)
 - getting raw mode to work may be a problem and may require some
length-encoding hacks
 - injecting protected (software encrypted) frames might be a problem

Either way you're at the mercy of firmware blob :)
