Upon forwarding frames from Rx to Tx in mesh, driver clones the skb.
It zeros the tx_info and doesn't set hw_queue correctly. It then
enqueues
the frame in queue 0 (VOICE) instead of the correct queue.
Upon re-queue of this frame, driver inserts it to the correct queue
(e.g. BE).
After that, driver dequeue frames from 2 different queues and sends
them out of order.
To fix this, driver will set the tx_info->hw_queue to the correct
queue when cloning the skb.
Makes sense, but the subject is a bit misleading - can you come up with
a better one?
