Backport following WiFi fixes to v3.2:
1. Add support for STA HT2040 coexist management
2. Add support for WPA2 improvements
3. Disallow HT rate when unicast/mcast cipher is TKIP/WEP
4. Add support for signal test
5. Fix the bug that WPS fails when AP is encrypted
1. fix the bug block scan tiemout before scan finish
2. make menuconfig can set the WiFi mgmt short buffer num
3. modify wifi reason code
4. fix the bug PMK recal too long
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.
Fix following WiFi bugs:
1. Shouldn't scan when connect
2. Check beacon length in modem sleep
3. Fix the bug that AP may deauth wrong station when inactivity timer expires
4. Fix the bug that WiFi assert the system when receiving empty MCS in association response frame
This is no longer required since the functions automatically get
pulled in based on the usage. A quick summary of footprint
comparisions before and after these set of patches is shown below:
Hello-World: (simplified for readability)
old Total image size:~ 104902 bytes (.bin may be padded larger)
old Total image size:~ 105254 bytes (.bin may be padded larger)
Per-archive contributions to ELF file:
Archive File DRAM .data & .bss IRAM Flash code & rodata Total
old libesp32.a 1973 177 4445 3939 2267 12801
new libesp32.a 1973 185 4473 3939 2267 12837
new libnvs_flash.a 0 92 0 274 8 374
new libstdc++.a 0 0 0 24 0 24
For some reason, nvs_flash.a (~400bytes) gets pulled in (particularly
the nvs_flash_init() function).
Power-Save: (simplified for readability)
old Total image size:~ 421347 bytes (.bin may be padded larger)
old Total image size:~ 421235 bytes (.bin may be padded larger)
old libtcpip_adapter.a 0 81 0 1947 115 2143
new libtcpip_adapter.a 0 69 0 1897 115 2081
The size actually shrinks a bit, since the AP interface function
doesn't get pulled in.
If static tx buffer is selected, WiFi tx buffers are allocated when WiFi is initialized and released
when WiFi is de-initialized. If dynamic tx buffer is selected, WiFi tx buffer is allocated when tx
data is delivered from LWIP to WiFi and released when tx data is sent out by WiFi.
The size of each static tx buffers is fixed to about 1.6KB and the size of dynamic tx buffers is
depend on the length of the data delivered from LWIP.
If PSRAM is enabled, "STATIC" should be selected to guarantee enough WiFi tx buffers.
If PSRAM is disabled, "DYNAMIC" should be selected to improve the utilization of RAM.
If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack
of WiFi. Otherwise linker errors on WiFi symbols should help give a
clue as to what is broken.
