Subject: [PATCHv2 1/2] nl80211: vendor-cmd: qca: add command for ap power save
Date:   Mon, 24 Aug 2020 13:56:28 +0530
Message-Id: <1598257589-19091-1-git-send-email-vnaralas@codeaurora.org>
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

AP power save feature is to save power in AP mode, where AP goes
to power save mode when no stations associate to it and comes out
of power save when any station associate to AP.

This patch is to add vendor command support to enable/disable
ap power save.

An example of usage: iw dev wlanx vendor send 0x1374 0x4a ap-ps <val>

0x1374: vendor id
0x4a: vendor subcmd id
val: 0 - disable power save
     1 - enable power save
