Re: [netmod] for a future rfc6991bis

Hi Tom, Juergen, 
I agree with Juergen - we went through this discussion with ietf-routing-types (RFC 8294) and came to the same conclusion. We kept, the generic link-access-type enum but I believe it is, heretofore, unused. 
Thanks,
Acee

    Tom,

    since states are often protocol specific, I believe we are better off
    with having states defined with protocol specific semantics. If you go
    for generic states, then you end up with mappings of generic states to
    protocol specific states, which are often non-trivial to get right and
    meaningful.
