From e1b3ec1a2a336c328c336cfa5485a5f0484cc90d Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Mon, 29 Mar 2010 12:18:34 +0200 Subject: mac80211: explicitly disable/enable QoS Add interface to disable/enable QoS (aka WMM or WME). Currently drivers enable it explicitly when ->conf_tx method is called, and newer disable. Disabling is needed for some APs, which do not support QoS, such we should send QoS frames to them.

This can aid debugging what is going on in mac80211 in interaction with drivers, since we can now see what drivers call and not just what mac80211 calls in the driver.
