+If 1 then for a packet with a well-formed MPLS label stack the
+bottom-of-stack bit indicates that the outer label stack entry is also
+the inner-most label stack entry and thus that is that there is only one
+label stack entry present.  Conversely, if 0 then for a packet with a
+well-formed MPLS label stack the bottom-of-stack bit indicates that the
+outer label stack entry is not the inner-most label stack entry and
+thus there is more than one label stack entry present.
