3. disable/enable agc to mac deinit/init (0d58779)
update PHY lib to 4007
There's a bug that cause BLE assert by following scenario:
1. If Wifi start softap and ble is working
2. If wifi start station, but do not use normal station operation, such
as just use espnow, while ble is working
3. Any other scenario, that wifi works without use software coexist
operation, while BLE is working(such as do advertising and ...)
Update librtc.a to V240:
update librtc.a to fix wlan mask rx of Wifi and bluetooth coexistence,
the error wlan mask will cause the bugs above.
1. Fix interrupt watchdog timeout in bluetooth "btdm_bb_isr" (e6431f2)

Fix some wifi bugs(abbd416e)
1. Enable RX BAR
2. Fix the bug that ESP32 AP negotiates with iphone to 11g
3. Fix the bug that ESP32 STA has ap_loss because CMCC AP contains two SSID
1. fix failture of mesh stop caused by block-sending.
2. fix when FIXED_ROOT is set, 2nd layer devices can not receive mesh event ESP_ERR_MESH_NO_PARENT_FOUND.
3. fix when FIXED_ROOT is set and the root turns off mesh function, 2nd layer devices do not look for new parents.
4. add APIs esp_mesh_disconnect() and esp_mesh_connect().
5. disconnect from parent/router when the DSSS channel in received beacon is different from the home channel.
6. remove nvs task to release 3k bytes memory.
fix the bug that if station (sleep is enabled) and sniffer are enabled at the same time,
when disable sniffer, station will never enable phy and rf again.
1. fix ap_loss that occurs when the parent turns off the mesh function and becomes a normal WiFi with a different SSID.
2. add an event MESH_EVENT_NETWORK_STATE that contains information about whether there is a root in the current network.
3. modify the mechanism of mesh IE update.
4. fix a problem in the process of re-voting to select the root, the device that does not meet the conditions of being a root votes for itself.
5. fix an issue that occurs in esp_mesh_recv_toDS() when stopping the mesh.
6. when the user specifies a parent for the device, the device will set the authmode and password of its AP mode to the same value as the specified parent.
7. add two disconnected reason codes MESH_REASON_EMPTY_PASSWORD and MESH_REASON_PARENT_UNENCRYPTED.
Fix some WiFi bugs (5bb80782):
1. Fix the bug that MIC verification fails on soft-AP mode
2. Modify mesh root to have same behavior as normal WiFi STA in state change
3. Fix the bug that sniffer can't catch control packets
4. Fix crash bug in soft-AP mode
5. Fix ACM(Admission Control Management) bug
bugfix:
1. fix the bug by resolve previous coexist hw blocking bug,
it may cause some assert like rwble.c (64,0) 222
2. resolve the bug reduce ble scan performance.
feature:
1. update version to v1.1.0
Several bugfix/optimizations about blockack session setup (a3be6390)
1. Fix the bug that ESP32 will reject the retry AddBA request frame
if AddBA response frame is failed to sent by WiFi LMAC
2. Fix the bug that AddBA request retrys too frequently
3. Forbid BA session setup for VO queue related TID
fix the bug following:
1. when software coexist working, there's a little ratio cause wifi task watchdog timeout
2. when software coexist working, there's a little ratio cause bluetooth cannot receive anything.
Known issues:
1. there's still a bug occurs with a very very low ratio cause bluetooth cannot receive anything.
The reproduce interval may great than 3days ~ 1week via 7x24 hours heavy testing.
MR !565
1. suppport mesh type, mesh ID, router and IE crypt func&key at any time after mesh is initalized.
2. support modify parent at any time after mesh is configured.
3. fix issues in root conflicts handling.
4. modify mesh nvs storage type same as Wi-Fi.
5. add max length of beacon to menuconfig.
6. add check for the channel value in the received beacon to filter out APs without DSSS.
