From c74114d7d51521bd785bf6aa0f90ee87d99bee8a Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 8 Sep 2020 14:36:55 +0200 Subject: mac80211: remove tx status call to ieee80211_sta_register_airtime All drivers using airtime fairness are calling ieee80211_sta_register_airtime directly, now they must. Document this as well.
