wpa_cli wps_reg <AP BSSID> <AP PIN>
(example: wpa_cli wps_reg 02:34:56:78:9a:bc 12345670)
Scanning
--------
Scan results ('wpa_cli scan_results' or 'wpa_cli bss <idx>') include a
flags field that is used to indicate whether the BSS support WPS. If
the AP support WPS, but has not recently activated a Registrar, [WPS]
flag will be included. If PIN method has been recently selected,
[WPS-PIN] is shown instead. Similarly, [WPS-PBC] is shown if PBC mode
is in progress. GUI programs can use these as triggers for suggesting
a guided WPS configuration to the user.
