wifi_station_wps_start() calls esp_wifi_disconnect() to leave a previously connected AP before scanning for WPS registrars. When the STA is already connected, the async disconnect event triggers wps_sm_notify_deauth() which incorrectly treats it as a handshake failure, disabling WPS entirely. Guard wps_handle_failure() so it only fires when wps_get_status() is WPS_STATUS_PENDING, i.e. the STA has found a WPS AP and is actively in the M1-M8 exchange.
'wpa_supplicant'
This component contains the upstream wpa_supplicant ported for ESP family of platforms. The code is tightly coupled with esp_wifi component which has ESP WiFi libraries and header files that are used in ported supplicant.
ESP uses MbedTLS as crypto library therefore MbedTLS component is also required for some features to work(see ESP_WIFI_MBEDTLS_CRYPTO).
To port it for different OS, esp_wifi and wpa_supplicant should be picked up a whole system(preferably with MbedTLS if we want all features to work.)
