From 0c7e477c666e767f231fafe08e117669c64e5e14 Mon Sep 17 00:00:00 2001 From: Janusz Dziedzic Date: Sat, 24 Jan 2015 12:14:52 +0200 Subject: [PATCH] ath10k: implement uapsd autotrigger command New wmi-tlv firmware for qca6174 has u-UAPSD autotrigger service. If it is enabled firmware generates trigger frames automatically as configured.
