+Subject: [PATCH] wpa_supplicant: support Multi-AP backhaul STA onboarding
+
+The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
+backhaul STA through WPS. To enable this, the backhaul STA needs to add
+a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
+that indicates it supports the Multi-AP backhaul STA role. The registrar
+(if it support Multi-AP onboarding) will respond to that with a WSC M8
+message that also contains the Multi-AP IE, and that contains the
+credentials for the backhaul SSID (which may be different from the SSID
+on which WPS is performed).
+
+Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
+set via control interface's new multi_ap=1 parameter of WPS_PBC call.
+multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
+Thus, if the AP does not support Multi-AP, association will fail and
+WPS will be terminated.
+
+Only wps_pbc is supported.
+
+The multi_ap argument is only added to the socket interface, not to the
+dbus interface.
