I have no idea what these are, nor do I actually want to care much...
You presumably use Felix's active monitor mode?

I think you should ask yourself if this makes sense in the normal wifi
context... :-)

It actually seems like it *does* make sense, so it should have an
appropriate description for that, but I'm a bit worried about IBSS in
sta_process.

Also I've tried to keep the code in the file sequential, so this patch
should be moving ieee80211_rx_h_decrypt() itself as well.
