Message-ID: <20160628111510.8857-1-yanivma@ti.com> Date: Tue, 28 Jun 2016 14:15:03 +0300 From: Yaniv Machani <yanivma@...com> To: <linux-kernel@...r.kernel.org> CC: Meirav Kama <meiravk@...com>, Johannes Berg <johannes@...solutions.net>, "David S. Miller" <davem@...emloft.net>, <linux-wireless@...r.kernel.org>, <netdev@...r.kernel.org> Subject: [PATCH] mac80211: rx: frames received out of order From: Meirav Kama <meiravk@...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.
