According to Ivo, we cannot be totally sure that the device has sent
the frame into the air, so no actual ACK is reported back to mac80211.

The hostapd hack works, as long as the stations are not very far from
the AP, and thus not 'too many retries' need to be sent.

AFAIK, this is not optimal at all, so I don't go around and say 'it
works'. It may or may not work in your case.
If possible, test and report back your findings.
