MR!495
1. add MESH_EVENT_SCAN_DONE event.
2. add APIs esp_mesh_scan_get_ap_record() and
esp_mesh_scan_get_ap_ie_len() to get scan results.
3. modify API esp_mesh_set_self_organized() by adding parameter
"select_parent".
4. modify API esp_mesh_set_parent() by adding parameter
"parent_mesh_id".
5. if self is set as Root-Fixed, ignore root conflicts.
1. Update libphy.a to v3900 (phy submodule commit: 4c02a1dc5)
2. Update librtc.a to v238 (rct submodule commit: ba66f971)
3. Update wifi lib to include following changes (fa8f8c64)
- add scan_method, sort_method and threshold when invoke esp_wifi_get_config()
- add rssi of each STA in softAP list
- add country information in scan result
- add noise floor in rx pkt
1. use FRC2 timer instead of WDEV_NOW() for modem sleep to calculate
TBTT time to fix the bug that miss beacon leads to incorrect
TBTT(34cfb0f1)
2. add rssi to sta rx probe req(1aba340d)
3. allocate mimo packet to internal memory(ce378ce9)
4. remove rc when ap not found(37058c03)
1. fix issues on sending beacon caused by too much tx retries on other packets.
2. modify not to scan if rc exists when connect.
3. modify scan dwell time to default 120ms fo root.
1. fix a bug in initliazing map beacon interval.
2. fix not send MESH_EVENT_ROUTING_TABLE_REMOVE when MESH_NWK_CHILD_DISCONNECTED.
3. fix a bug in returning roots ie len.
1. fix TKIP counter measure fail issue(d63b857d)
2. support WPS enrollee in APSTA mode(b868d1dd)
3. fix sniffer stop cause ap not rx data issue(eefe22d0)
4. add an API to enable/disable ap rx probe request event(f9df83d7)
1. PHY383.0 (144a41def)
1）add IRAM_ATTR to the API who running in interrupt.
2) add pwdet_sar2_init() to phy_pwdet_onetime_en() for configuring SAR2 to power detect。
2. PHY380.0 (121493c6)
last version PHY379.0 can take watchdog.
1. PHY379.0 (4bdc3f76)
Added two functions in PHY API for disable interrupts.
2. PHY378.0 (3e6afecd)
add rfcal data checking to PHY
3. PHY377.0 (9cebd864)
do not use some rom function which used ets_delay_us().
add rfcal data checking API.
add TX Power ontime tracking API.
4. RTC V236 (d616fe55)
update VDD33 driver
5. PHY V371.0 (07188d4a)
add rx sense API
add multi-ant API
fix a problem for last version PHY 366.0.
PHY366.0 will make TX Power tracking fail in sometime
1. fix the bug that in sniffer mode last descriptor is null when
receive incorrect packets at first(9adebde6)
2. revert bugfix/inctive_time_happen_in_softAP(eee6c4b5)
