esp-open-rtos/open_esplibs/libmain/user_interface.c
Our Air Quality b39df7f91e open_esplibs user_interface: source code for functions touching the struct netif. (#275) 
Add source code for functions touching the struct netif to better support lwip development: sdk_wifi_get_ip_info, sdk_wifi_set_ip_info, sdk_wifi_get_macaddr, sdk_wifi_set_macaddr.

Also code for sdk_wifi_station_get_connect_status.

Also code for wifi_get_sleep_type and set_sleep_type, noting wifi_set_sleep_type returns a bool success flag, and implement wifi_get_sleep_type using sdk_pm_get_sleep_type.
