rtw88: coex: fix A2DP stutters while WL busy + WL scan
While WL scan, WL is more high priority than BT. The packets from AP will be a big interference to A2DP. It will lead to A2DP stutters. Stop answering CTS to AP to decrease AP's packets Tx while WL scan + WL busy. Enable BT AFH feature to make BT leave away from WL channel. Desired BT firmware BT-COEX version: 0x1c Desired WL firmware version: 9.9.x Signed-off-by: Ching-Te Ku <ku920601@realtek.com> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20210319054218.3319-8-pkshih@realtek.com
