3. Fix the bug that ESP32 station fails to connect some APs, such as Xiaomi hotspot etc,
after reset.
1. during parent selection, when scanning a MAP without ext-assoc IE, it will be handled as it has the same router BSSID as itself.
2. for MAP, when its client leaves, always post SYSTEM_EVENT_AP_STADISCONNECTED to mesh layer regardless of whether the client has passed the encrypted authentication or not.
1. detect and fix root conflicts when router BSSID is not set.
2. when root can not connect to the router due to NO_MORE_STAS(reason code:5), root will stop re-connection and perform MESH_NWK_LOOK_FOR_NETWORK.
3. wifi: fix the disconnection caused by receiving a deauth frame from non-parent node during scanning.
4. fix routing table redundant issue.
5. modify the max routes limitation from 300 to 1000.
6. wifi: fix ap does not deauth sta which has not completed the 4-way handshake.
1. when no parent is found, send probe request via broadcast.
2. fix memory leak caused by the remove announcement being sent is not released when esp_mesh_stop() is called.
3. fix modify IE encrypt after mesh is started.
4. ignore esp_mesh_connect() if mesh automatic reconnection is enabled.
5. fix reason is cleared before vote is done.
1. fix STAs can not detect disconnection from AP when encrypt transmission is used.
2. fix can not find hidden APs.
3. for root, modify the active scan time to 120ms.
4. remove all rc when clear parent Wi-Fi configuration.
5. fix error in checking Wi-Fi commit ID.
1. support csa function
- users can obtain the new channel through the event MESH_EVENT_CHANNEL_SWITCH.
- the entire network will be moved to the same channel as the router without user intervention.
- if no router is in the network, users can call esp_mesh_switch_channel() on the root side to move the entire network to their desired channel.
2. support not configuring the network channel.
3. support not configuring the router BSSID even if the router is hidden.
4. add allow_channel_switch to mesh configuration.
- if the channel is not specified, this value will be ignored.
- if the channel is specified and this value is set, when "fail" (mesh_attempts_t) times of parent selection or look for networks are reached,
device will change to perform a full channel scan for networks that could join.
- if the channel is specified and this value is set to 0, when a root is not elected, channel switch is not allowed. but when a root appears,
the root performs a full channel scan during the process of connecting to the router, so even allow_channel_switch is set to 0, the root may
still switch channel and eventually the entire network changes channel.
5. add allow_router_switch to mesh router configuration.
- if the BSSID of router is not specified, this value will be ignored.
- if the BSSID of router is specified and this value is set, when the router of this specified BSSID fails to be found after "fail"
(mesh_attempts_t) times, the entire network is allowed to switch to another router with the same SSID.
6. modify the root to perform a full channel scan when esp_wifi_connect().
7. support handling beacon without IE of DS Parameter Set.
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

4. Fix crash bug in soft-AP mode
5. Fix ACM(Admission Control Management) bug
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
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.

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.
fix some modem sleep bugs(f9a3bf511)

3. Change freq_offset step from 16k to 4k
4. void phy_chan_filt_set(bool filt_en, bool merge_en)
