+Subject: [PATCH] mac80211: split beacon retrieval functions
+
+Split __ieee80211_beacon_get() into a separate function for AP mode
+ieee80211_beacon_get_ap().
+Also, move the code common to all modes (AP, adhoc and mesh) to
+a separate function ieee80211_beacon_get_finish().

+Subject: [PATCH] nl80211: MBSSID and EMA support in AP mode
+
+Add new attributes to configure support for multiple BSSID
+and advanced multi-BSSID advertisements (EMA) in AP mode.
+
+- NL80211_ATTR_MBSSID_CONFIG used for per interface configuration.
+- NL80211_ATTR_MBSSID_ELEMS used to MBSSID elements for beacons.
+
+Memory for the elements is allocated dynamically. This change frees
+the memory in existing functions which call nl80211_parse_beacon(),
+a comment is added to indicate the new references to do the same.
