From d86aa50608e1387cbd52ffc3905cf45e533e3991 Mon Sep 17 00:00:00 2001 From: Yan-Hsuan Chuang Date: Thu, 11 May 2017 14:01:11 -0500 Subject: [PATCH] rtlwifi: btcoex: 21a 2ant: refine btc8821a2ant_action_hid_a2dp For hid a2dp profiling, decrease the bt power because of the distance of bt is usually short, and do not adjust the wifi duration to a longer period since it may be interrupted by bt easily, set tdma instead.
