Is this behavior expected and we need to handle that case in rt2x00 or is it more likely a bug? At least I thought the select_queue implementation in mac80211 was meant to always pick the same tx queue for skbs with the same priority and hence it shouldn't happen that frames with the same TID are queued into different tx queues. This behavior seems to have changed already a while ago with the patch "net: Use sk_tx_queue_mapping for connected sockets" (CC'ing Krishna & netdev).
