#1432866 — [PATCH] mac80211: rx: frames received out of order

From: Meirav Kama <meiravk@ti.com>

MP received data frames from another MP. Frames are forwarded
from Rx to Tx to be transmitted to a third MP.
Upon cloning the skb, the tx_info was zeroed, and the
hw_queue wasn't set correctly, causing frames to be
inserted to queue 0 (VOICE). If re-queue occurred for some
reason, frame will be inserted to correct queue 2 (BE).
In this case frames are now dequeued from 2 different queues and
sent out of order.

Please rewrite this commit log in active voice, and explain the fix
too.
