Description sebastien.deronne 2016-06-07 15:55:45 UTC

It has been reported by Ioannis that SendBlockAckAfterAmpdu is called even if the A-MPDU frame is not destined to that node, resulting in a simulation failure:
assert failed. cond="i != m_bAckCaches.end ()

There is indeed a misplacement of the if condition in MacLow::DeaggregateAmpduAndReceive. Patch will follow.
