mac80211: update A-MPDU flag on tx dequeue
The sequence number counter is used to derive the starting sequence number. Since that counter is updated on tx dequeue, the A-MPDU flag needs to be up to date at the tme of dequeue as well. This patch prevents sending more A-MPDU frames after the session has been terminated and also ensures that aggregation starts right after the session has been established Fixes: bb42f2d13ffc ("mac80211: Move reorder-sensitive TX handlers to after TXQ dequeue") Signed-off-by: Felix Fietkau <nbd@nbd.name> Acked-by: Toke Høiland-Jørgensen <toke@toke.dk> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
