From a8570896b962dc2b8e7787c59a45521e64b187e2 Mon Sep 17 00:00:00 2001 From: Yan-Hsuan Chuang Date: Tue, 4 Apr 2017 11:50:04 -0500 Subject: [PATCH] rtlwifi: btcoex: 23b 2ant: turn off ps and tdma mechanism when in concurrent mode When wifi is in concurrent mode, we can not distinguish if it is the real PS or just a fake one by sending null data, so we turn it off in case of miracast scenario.
