Subject: [PATCH] wpa_supplicant/dbus AP: Add support for WPS Internal
Registrar.
When in AP mode, wpa_supplicant is now enabling WPS (only Internal
Registrar). WPS.Start() call can be used to initiate WPS negotiation
similarly to how this is done in station mode.
This was done to ctrl_iface by Jouni Malinen on April 21, 2009 (commit
3ec97afe571f159ea95213262c1c6b89965827d4)
