From 1a589bd5be9260f59adf34e0a6dc21644f3cf74b Mon Sep 17 00:00:00 2001 From: Ching-Te Ku Date: Thu, 26 Nov 2020 10:10:51 +0800 Subject: rtw88: coex: add debug message Add message for debugging usage and the program flow is no change. Add a variable reserved for WLAN firmware synchronize. Add a group of variable to save BT packet counter, it will be assigned as mechanism judgment in the future. Now it is just for debug usage.
