+Subject: mac80211: set mcast-rate for mesh point interfaces
+
+In order to set the multicast rate for mesh point interfaces the "mesh join"
+was made explicit and moved to mac80211_setup_vif(), similar to how it is
+done for IBSS interfaces.
+
+Previously, the mesh join was made implicit in case authentication (i.e.
+$key) was not used when creating the interface in mac80211_prepare_vif(),
+while using authentication would create the interface first, then join
+later in mac80211_setup_vif() by starting authsae.
