+	Setting plink_action [block|open], when 802.11s mesh-interface comes up.
+	Define filterpolicy in uci wireless.<wifi-iface>.macfilter=[disable|deny|allow].
+	Deny sets iw dev <device> station set <mac> plink_action block, and
+	allow sets iw dev <device> mesh_param mesh_auto_open_plink=0 and iw dev <device> station set <mac> plink_action open.
+	List MAC adresses (divided by spaces) in uci wireless.<wifi-iface>.maclist.
