+ * plumbed, taking it up and down depending on whether it's currently in use
+ * or not.  v6 interfaces are not plumbed initially; when we decide a link
+ * should be active (and its llp tells us to do v6), we'll mark the (already
+ * existing) v4 interface up, and 'plumb up' the v6 interface.  Conversely,
+ * when a link is no longer active, we 'down unplumb' the v6 interface, but
