Re: [netmod] for a future rfc6991bis

Many (most?) routing protocols introduce a state - up, down +- coming
up, going down, maintenance and such like, used for interfaces, tunnels,
adjacencies and the like.  It is a shame that there are so many
variations on this although to some extent this reflects the differences
in the protocols.  And some use types, others identity.
