wifi: rtw89: coex: Solved BT PAN profile idle decrease Wi-Fi throughput
Some Bluetooth device will make up connection as PAN link, though the
connection is idle, it will still report the PAN link is active. The
coexistence mechanism will enable TDMA to protect the PAN, it makes
Wi-Fi throughput degrade at least 50%. But the link is idle, don't
need so much bandwidth. Add TDMA case to let Wi-Fi can do traffic 80%
bandwidth.
