From: Avraham Stern <avraham.stern@xxxxxxxxx>
Some drivers do not support having two station interfaces, so the
fact that wpa_supplicant always creates a new interface in station
mode, even if it will be used as another type of interface, may
prevent wpa_supplicant from creating new interfaces.
Allow setting the interface type when a new interface is created
so that interfaces of supported types can be created.
Currently supported types are station ("sta") and AP ("ap"). If the
interface type is not specified, a station interface will be created.
