+	  This option enables BLA (Bridge Loop Avoidance), a mechanism
+	  to avoid Ethernet frames looping when mesh nodes are connected
+	  to both the same LAN and the same mesh. If you will never use
+	  more than one mesh node in the same LAN, you can safely remove
+	  this feature and save some space.
