1. Improve WiFi throughput in some Classic BT scienarios(idle, inquire scan,
connected, sniff, a2dp pause, etc).
2. Support WiFi + Classic BT + BLE mesh coexistence scienario.
3. Improve WiFi scan and connect succeed ratio in coexistence scienario.
4. Do not support to choose software coexistence preference anymore for it is
determined according to coexistence scienario automatically.

connection events. With a lower level of clock accuracy(e.g. 500ppm over 250ppm), the slave

increase of power consumption but a higher level of robustness in keeping connected. According
