Check if atf has been disabled in __ieee80211_schedule_txq() in order to avoid a given sta is always put to the beginning of the active_txqs list and never moved to the end since deficit is not decremented in ieee80211_sta_register_airtime() Fixes: b4809e9484da1 ("mac80211: Add airtime accounting and scheduling to TXQs") Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Acked-by: Toke Høiland-Jørgensen <toke@toke.dk> Link: https://lore.kernel.org/r/93889406c50f1416214c079ca0b8c9faecc5143e.1608975195.git.lorenzo@kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
