Yes. If A-MSDU in A-MPDU is not supported, dealing with starting and
stopping of A-MPDU sessions leaves all kinds of nasty corner cases
(since the txq is not flushed between sessions). In that case it's
better to just leave it disabled from that point on.

Fair enough. You should be able to deal with it with the SSN, but that
might be difficult.

Actually, mac80211 on its own assigns the seqno so frames already on
the txq would not become part of the session, so we should be OK
without much effort?

seqno is assigned on txq dequeue, not enqueue.
