Subject: [PATCH] rtw88: coex: set 4 slot TDMA for BT link and WL busy
Date: Wed, 30 Dec 2020 11:36:02 +0800	[thread overview]
Message-ID: <20201230033602.13636-1-pkshih@realtek.com> (raw)

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.
