From 4ced3f74dae18715920cb680098ec7ff4345d0a3 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 19 Jul 2010 16:39:04 +0200 Subject: mac80211: move QoS-enable to BSS info Ever since commit e1b3ec1a2a336c328c336cfa5485a5f0484cc90d Author: Stanislaw Gruszka Date: Mon Mar 29 12:18:34 2010 +0200 mac80211: explicitly disable/enable QoS mac80211 is telling drivers, in particular iwlwifi, whether QoS is enabled or not. However, this is only relevant for station mode, since only then will any device send nullfunc frames and need to know whether they should be QoS frames or not. In other modes, there are (currently) no frames the device is supposed to send. When you now consider virtual interfaces, it becomes apparent that the current mechanism is inadequate since it enables/disables QoS on a global scale, where for nullfunc frames it has to be on a per-interface scale. Due to the above considerations, we can change the way mac80211 advertises the QoS state to drivers to only ever advertise it as "off" in station mode, and make it a per-BSS setting.
