From 4a755a8ef46d5779a596d6ad1b4ccc43b756832a Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Thu, 3 Jul 2014 20:46:35 +0300 Subject: [PATCH] iwlwifi: mvm: disable CTS to Self Firmware folks seem say that this flag can make trouble. Drop it. The advantage of CTS to self is that it slightly reduces the cost of the protection, but make the protection less reliable.
