From aae1e8f5a0f05e0965b56a3cf6bfd2686577e817 Mon Sep 17 00:00:00 2001 From: Yan-Hsuan Chuang Date: Thu, 13 Apr 2017 13:07:04 -0500 Subject: [PATCH] rtlwifi: btcoex: 21a 2ant: set coex table and tdma when bt inquiry Instead of just setting the coex table directly, we check if the wifi is under some important activity (scanning|roaming|linking) and mark the packets as high priority in that case.
