Subject: [PATCH] rtlwifi: btcoex: 23b 1ant: turn off ps and tdma mechanism when concurrent mode
Git-commit: 86aeb82563b7b20f8b8050a065ce907bd3a2a4b1
Patch-mainline: v4.13-rc1
References: FATE#326906
When wifi is under 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.
