From c42055105785580563535e6d3143cad95c7ac7ee Mon Sep 17 00:00:00 2001 From: Yuan-Chi Pang Date: Thu, 6 Sep 2018 16:57:48 +0800 Subject: mac80211: fix TX status reporting for ieee80211s TX status reporting to ieee80211s is through ieee80211s_update_metric. There are two problems about ieee80211s_update_metric: 1. The purpose is to estimate the fail probability to a specific link. No need to restrict to data frame. 2. Current implementation does not work if wireless driver does not pass tx_status with skb. Fix this by removing ieee80211_is_data condition, passing ieee80211_tx_status directly to ieee80211s_update_metric, and putting it in both __ieee80211_tx_status and ieee80211_tx_status_ext.
