In theory you have TID X receiving address queues. Number of TIDs is 16 yet for the aggregation on 8 are relevant.Let say your AP supports 32 connected stations so you need 256 queues for to keep packets in order. Of course in HW you keep smaller number..etc. Ron will send RX AMSDU aggregation patches at the beginning of the next week, then he will work on TX side. I suggest that in that context we can open the discussion how to solve the QoS queues and Qdisc cleanly. Tomas > johannes >
