1. When WIFI task or other high priority task blocks the Bluetooth task, ACL RX buffer will use up, ACL RX buffer ptr will point to null and will never point to a valid adress. Causing errors in Bluetooth.
2. hcimsgs.h used whether flow control is on or off
Problem Decribe
The problem happenned when do wps with a mikrotik router
1. router always want to do connect with 32 without EAP-WSC step
2. after 4 way timeour, 32 crash
Root Cause
The reason why can not start EAP-WSC step is router's check method is RSN > WPA > WPS, when it found there include RSN and WPS in assoc, it will choice do 4 way rather than WPS
The reason of second problem is 32's EAPOL start timer didn't stop and send EAPOL start to a null pointer
Soultion
1. remove RSN and WPA ie when do WPS step
2. check mac address's pointer before send EAPOL start

Fix following WiFi bugs:
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
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 earlier change this component was decoupled from freertos and hence
regression was introduced which changed default placement to flash. Some
device drivers make use of ringbuffer while flash cache is being disabled
and hence default placement should instead be internal memory.

1. fix some bugs by previous coex hw blocking bugfix,
such like, rwble.c (64, 0) line 222
2. fix bug that ble scan performance is very low when software coexist
is working.
3. update libcoexist version to v1.1.0
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. 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
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
In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.
Problem Description
The reporduce steps are as follows:
1. put more than one same ssid AP in the environment;
2. set the STA mac address in one of the APs blacklist, and make sure the AP is closest to STA;
3. set the scan method in station config as all channel scan;
4. try to connect the AP which set STA in blacklist
Phenmenon
STA fail to connect after send auth or assoc with a wrong status code, but no disconnect event report and can not connect the next one in the envrionment
Root Cause
Because there are some same ssid APs in the evnrionment, when do all channel scan, it will collect all the matched AP in rc list, because rc list is not empty, so it would send disconnect event, however, we didn't do other step such as connect to other one

_rtc_data_{start,end} can now describe data placed into RTC_FAST
segment, if CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled.
Use new _rtc_slow_length symbol instead.
fix the bug following:
1. after disable bluetooth controller, wifi cannot TX/RX any packets.
2. when software coexist working, there's a little ratio cause wifi task watchdog timeout
3. when software coexist working, there's a little ratio cause bluetooth cannot receive anything.
feature:
1. add libbtdm_app.a git commit local and remote checking
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.
Previously, esp-touch only supports multicast packets which are
transmitted from cellphone. But for most dual frequency routers
whose SSIDs of 5G and 2.4G are the same, broadcast packets are
forwarded from 5G interface to 2.4G interface while multicast
packets are not. In order to make esp-touch work when cellphone
connects to 5G interface of these routers, esp-touch is improved
to support both multicast and broadcast packets. Meanwhile, new
APP which is compiled with Andriod or IOS library(>= v0.3.6.2)
must be used in this situation. Note that for some routers,
broadcast and multicast packets are forwarded from 5G interface
to 2.4G interface only when another WiFi device is connected to
2.4G interface of the router. Old APP which is compiled with
Android or IOS library(< v0.3.6.2) also works with this improvement
when cellphone connects to 2.4G interface of the router.
The Android and IOS library of new esp-touch APP is now available
on Github.

IOS: https://github.com/EspressifApp/EsptouchForIOS
Four internal APIs `esp_http_client_connect()`, `http_client_prepare_first_line()`, `esp_http_client_request_send()` and
`esp_http_client_send_post_data()` API have been added for perfoming connection establishment (sync as well as async),
preparing first line, sending request and sending post data respectively.
In `transport_ssl`, `ssl_connect_async()` API has been added for establishing asynchronous connection.
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. modify manual networking example.
4. update header file.
5. fix issues in root conflicts handling.
6. add max length of beacon to menuconfig.
7. fix issue when received a beacon without DSSS.
Problem Description
set some of routers as the same ssid in the same channel, when 32 in the fast scan connect mode, there may no disconnect event report in that two sceanrio:
1. set the correct password and connect, if target router didn't report 32's auth req before timeout, the state machine change to init but no disconnect event report
2. set a wrong password, if router send disassoc or deauth after run, rather than wait 4 way handshake timeout, the state machine change to init but no disconnect event report
Root Cause
Because the routers are in the same channel, all of them are matched the ssid, so all of them can be instore in the rc list wait for connect, when the first one want to connect fail at auth or receive
disassoc or deauth when password wrong, the rc list is not empty, it can not send disconnect event because rc is not empty
Solution
1. put the fail the router in the blacklist
2. Judge whether there is another router can be connect, if it has, try to connect with the next one

gen_esp_err_to_name.py includes files like
components/lwip/include/apps/esp_ping.h as "apps/esp_ping.h" because all
subdirectories of "include" are used. If "components/lwip/include/apps"
is in the path of the compiler instead of "components/lwip/include" then
include "apps/esp_ping.h" will fail. This fix allows to process lines
like:
'// gen_esp_err_to_name.py: some text "esp_ping.h" some text'
in header files for overwriting the include.
Before LwIP was moved into a submodule, sntp and esp_ping were
available as the following includes:
#include "apps/sntp/sntp.h"
#include "esp_ping.h"
This commit makes header files available at the old location, and adds
a deprecation warning for sntp.h.
