wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS 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. This commit adds the multi_ap argument only to the control socket interface, not to the D-Bus interface. Since WPS associates with the fronthaul BSS instead of the backhaul BSS, we should not drop association if the AP announces fronthaul-only BSS. Still, we should only do that in the specific case of WPS. Therefore, add a check to multi_ap_process_assoc_resp() to allow association with a fronthaul-only BSS if and only if key_mgmt contains WPS.
