How did it used to work?
* monitor mode very specifically doesn't define output methods at all;
* there's no temporary nodes created when transmitting, so it all
simply ends up being dropped because no txnode was found.
So perhaps there was some path via the raw output method which no
longer is working. The _output() method supposedly permits BPF
injected packets to work by sending packets using a node ==
vap->iv_bss, but that can't possibly work with the existing monitor
mode because code in ieee80211.c doesn't set the output methods for
