From 39149911ba28d17b4657a9a65b3dc8ba54145ca0 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Sun, 14 Jul 2013 13:40:21 +0300 Subject: [PATCH] iwlwifi: mvm: don't use reduced Tx power when not applicable When we have only one antenna for BT and WiFi, reduced Tx power is irrelevant. Also, in loose scheme, we should not use reduced Tx power nor set the control mask to Tx power.
