Subject: [PATCH 2/4 2.6.33.y] iwlwifi: manage QoS by mac stack
Date: Fri, 11 Jun 2010 17:04:18 +0200

commit e61146e36b40fd9d346118c40285913236c329f3 upstream.

We activate/deactivate QoS and setup default queue parameters in iwlwifi
driver. Mac stack do the same, so we do not need repeat that work here.
Stack also will tell when disable QoS, this will fix driver when working
with older APs, that do not have QoS implemented.

Patch make "force = true" in iwl_active_qos() assuming we always want
to do with QoS what mac stack wish.

Patch also remove unused qos_cap bits, do not initialize qos_active = 0,
as we have it initialized to zero by kzalloc.

Subject: [PATCH 1/4 2.6.33.y] mac80211: explicitly disable/enable QoS
Date: Fri, 11 Jun 2010 17:04:17 +0200

commit e1b3ec1a2a336c328c336cfa5485a5f0484cc90d upstream.

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.

commit 76f273640134f3eb8257179cd5b3bc6ba5fe4a96 upstream.

If AP do not provide us supported rates before assiociation, send
all rates we are supporting instead of empty information element.
