From 9a5ab0f49f9fb16f73717cb7f434556aa3bac3fe Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Date: Thu, 19 Mar 2015 16:03:29 +0200 Subject: [PATCH] ath10k: fix rts profile for second rate series By default rts protection is enabled in firmware for the second rateset. Currently ath10k selects RTS profile (only for software retries), when legacy stations are associated or asked by mac80211. On congested environment, when AP is running in HT/VHT mode and there are no legacy clients associated, this will impact the robustness. Also enabling RTS protection only for second rateset will not impact performance on clear environment. Fix that.
