1. Modify esp_wifi_get_station_list to esp_wifi_ap_get_sta_list 2. Modify tcpip_adapter_get_station_list to tcpip_adapter_get_sta_list 3. Remove esp_wifi_free_station_list 4. Remove tcpip_adapter_free_station_list 5. Modify related data struct accordingly
While this may reduce esp_wifi.h file readability for people who don't have a "go to definition" function in their editors, this is needed to decouple esp_wifi and esp_event headers, and possibly other headers which may use wifi types in the future.
