Subject: [PATCH] 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")
