    Fix WPS IE in Probe Response frame to include proper Config Methods
values

    This attribute is supposed to indicate which methods the AP supports as
    an Enrollee for adding external Registrars. It was left to 0 when the
    AP code did not yet support external Registrars and was forgotten when
    the ER support was added.


Thank you,
    Andriy
