From 9fa290feb9797cf249943cbf228e3f2d0cecaa56 Mon Sep 17 00:00:00 2001 From: Ching-Te Ku Date: Tue, 12 Jan 2021 10:11:35 +0800 Subject: [PATCH] rtw88: coex: set 4 slot TDMA for BT link and WL busy To protect both of WL/BT performance while BT is under re-link state. 4-slot mode TDMA can make the re-link more sensitive and mitigate the WL throughput drop.
