-Subject: [PATCH] hostapd: Add Multi-AP protocol support
-
-The purpose of Multi-AP specification is to enable inter-operability
-across Wi-Fi access points (APs) from different vendors.
-
-This patch introduces one new configuration parameter 'multi_ap' to
-enable Multi-AP functionality and to configure the BSS as a backhaul
-and/or fronthaul BSS.
-
-Advertise vendor specific Multi-AP capabilities in (Re)Association
-Response frame, if Multi-AP functionality is enabled through the
-configuration parameter.
-
-A backhaul AP must support receiving both 3addr and 4addr frames from a
-backhaul STA, so create a VLAN for it just like is done for WDS, i.e.,
-by calling hostapd_set_wds_sta(). Since Multi-AP requires WPA2 (never
-WEP), we can safely call hostapd_set_wds_encryption() as well and we can
-reuse the entire WDS condition.
-
-To parse the Multi-AP Extension subelement, we use get_ie(): even though
-that function is meant for parsing IEs, it works for subelements.
