From d2d9c9b8de725e1006d3aa3d18678a732f5d3584 Mon Sep 17 00:00:00 2001 From: Vinith Kumar R Date: Fri, 22 Nov 2024 23:04:32 +0530 Subject: [PATCH] wifi: ath12k: Report proper tx completion status to mac80211 Currently Tx completion for few exception packets are received from firmware and the tx status updated to mac80211. The tx status values of HAL_WBM_REL_HTT_TX_COMP_STATUS_DROP and HAL_WBM_REL_HTT_TX_COMP_STATUS_TTL are considered as tx failure and reported as tx failure to mac80211. But these failure status is due to internal firmware tx drop and these packets were not tried to transmit in the air. In case of mesh this invalid tx status report might trigger mpath broken issue due to increase in mpath fail average. So do not report these tx status as tx failure instead free the skb by calling ieee80211_free_txskb(), and that will be accounted as dropped frame.
