From: Johannes Berg <johannes.berg@xxxxxxxxx> The temporary TX info flags need to be cleared if the frame will be processed through the TX handlers again, otherwise it can get messed up. This fixes a bug that happened when an aggregation session was stopped while the station was sleeping - some frames might get transmitted marked as aggregation erroneously without this fix.
