From: Balaji Pothunoori bpothuno@qti.qualcomm.com

[ Upstream commit 07ffb4497360ae8789f05555fec8171ee952304d ]

Data packets are not sent by STA in case of STA joined to non QOS AP (WMM disabled AP). This is happening because of STA is sending data packets to firmware from host with qos enabled along with non qos queue value(TID = 16). Due to qos enabled, firmware is discarding the packet.

This patch fixes this issue by updating the qos based on station WME capability field if WMM is disabled in AP.

This patch is required by 10.4 family chipsets like QCA4019/QCA9888/QCA9884/QCA99X0. Firmware Versoin : 10.4-3.5.1-00018.

For 10.2.4 family chipsets QCA988X/QCA9887 and QCA6174 this patch has no effect.
