Yes, MIC won't match (or well, in theory it could, but in practice..)
and if the original frame is available after failed hw-decryption
attempt, this is indeed all that's needed here. Some hardware designs
are not able to deliver the unmodified frame due to the way AES hwaccel
is implemented in them and that gets bit tricky to handle in software
for IEEE 802.11w.
