Right. So the way I saw this triggered was:

* 11n AMPDU-RX - non-aggregate frames wouldn't trigger this bug;
* one station TX'ing AMPDU frames via iperf tcp;
* another station (mostly) listening

That way the chance of the frame having a higher seqno enough to
trigger the condition would be higher.
