+Subject: [PATCH] wifi: mac80211: Add getter functions for vif MLD state
+
+As a preparation to support disabled/dormant links, add the
+following function:
+
+- ieee80211_vif_usable_links(): returns the bitmap of the links
+ that can be activated. Use this function in all the places that
+ the bitmap of the usable links is needed.
+
+- ieee80211_vif_is_mld(): returns true iff the vif is an MLD.
+ Use this function in all the places where an indication that the
+ connection is a MLD is needed.
