For my usage case I want specific unencrypted packets filtered by a MAC
address that isn't part of the authenticated network, so the reception
action needs to be effectively promisc a la Monitor mode, not just
"received management frames". But I guess it can be done with IFF_PROMISC.
By piping everything down "wlan0" normal packets will not have the
radiotap metadata on their capture, but presumably the abnormal packets
can have it via a special ethernet frame type + radiotap header. Maybe
it doesn't matter for any actual use.
