CRC is most likely FCS. And Physical ist most likely the PLCP CRC.

Not sure what mac80211 does for crypto errors, I expect you want to send
them up without having it decrypted, it'll attempt it and then do the
appropriate actions. Seems it should be possible to short-circuit that
somehow, but I don't know if it is right now.
