14. clear candidate settings if not receive candidate beacon within 8 seconds.
When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).
Backport following WiFi fixes to v3.2:

9. fix can not find hidden APs.
10. for root, modify the active scan time to 120ms.
11. remove all rc when clear parent Wi-Fi configuration.

13. fix modify IE encrypt after mesh is started.
14. ignore esp_mesh_connect() if mesh automatic reconnection is enabled.
15. fix reason is cleared before vote is done.
16. fix issues in the example of manual_networking when mesh network is encrypted.
17. detect and fix root conflicts when router BSSID is not set.
18. 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.
19. wifi: fix the disconnection caused by receiving a deauth frame from non-parent node during scanning.
20. fix routing table redundant issue due to the remove announcement is not 100% reliable.
21. modify the max routes limitation from 300 to 1000.
22. wifi: fix ap does not deauth the sta which has not yet completed the 4-way handshake but the max replay count is reached.
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.
1. start an esp_timer on entering sleep to acquire pm_lock before wake up from modem sleep
2. decrease the clock division of XTAL fed to bluetooth low power clock from 32us to 2us period to allow to work under 240MHz Max CPU frequency
3. decrease the minimum sleep duration threshold to allow shorter bluetooth modem sleep period, especially for BLE with short connection interval
4. reconfigure bluetooth baseband(BT-BB) settings after PHY/RF init upon waking up from modem sleep to avoid packet RX/TX performance degradation
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.
1. Original register mapping for LAN8720 has some registers that doesn't exist/support.
So just remove them, and fix the power and init function for LAN8720.
2. GPIO16 and GPIO17 is occupied by PSRAM, so only ETH_CLOCK_GPIO_IN mode is supported in that case if using PSRAM.
3. Fix bug of OTA failing with Ethernet
4. Fix bug of multicast with Ethernet
5. Fix potential memory leak
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.
Routine `spi_flash_cache2phys` sometimes return incorrect value,
resulting in failure in getting currently running ota partition.
This in turn aborts firmware update process.This issue was more
prominent with SPIRAM enabled cases.
Fix ensures proper cache guards during `spi_flash_cache2phys`, and
also for few other similar APIs.
In addition, `esp_ota_get_running_partition` has also been optimized
to save currently running partition for subsequent invocations.
Fixes https://github.com/espressif/esp-idf/issues/2451
In some cases, when data was just written into UART FIFO, transmitter
state could be still zero while the FIFO did contain some data.
This resulted in uart_tx_wait_idle occasionally returning before all
the data was sent out.
Fix by checking both UART transmitter state and TX FIFO count.
1. remove use EID to distinguish psram voltage
2. 1V8 64Mbit psram and 3V3 64Mbit psram use the same psram driver(standard spi interface)
3. set cs hold time register as 1
