From: Meirav Kama <meir...@ti.com>
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.
