Subject: [PATCH 5.16] mac80211: fix rate control for retransmitted frames
Date: Mon, 22 Nov 2021 21:43:23 +0100 [thread overview]
Message-ID: <20211122204323.9787-1-nbd@nbd.name> (raw)
Since retransmission clears info->control, rate control needs to be called
again, otherwise the driver might crash due to invalid rates.
Cc: stable@vger.kernel.org # 5.14+
Reported-by: Aaro Koskinen <aaro.koskinen@iki.fi>
Reported-by: Robert W <rwbugreport@lost-in-the-void.net>
Fixes: 03c3911d2d67 ("mac80211: call ieee80211_tx_h_rate_ctrl() when dequeue")
