From 81e60b2dfb2744ab6642c4aa62534b4f711fdc5d Mon Sep 17 00:00:00 2001 From: Aditya Kumar Singh Date: Tue, 27 Sep 2022 09:18:54 +0300 Subject: wifi: ath11k: stop tx queues immediately upon firmware exit Currently, recovery flag is set immediately upon firmware exit but tx queues are stopped once firmware arrives back and is ready which is during ath11k_core_restart. Once ieee80211 hw restart is completed, tx queues are resumed. If during the time delta between firmware exit and firmware ready, mac80211 send packets, currently ath11k will drop it since recovery flag will be set. But warning prints will come - "ath11k c000000.wifi: failed to transmit frame -108" If more tx packets are there, this could lead to flooding of above print. However, actually tx queues should be stopped immediately when firmware leaves. This will prevent packets to get dropped when firmware is recovering. Add fix to stop tx queues immediately after firmware exit.
