for IPv6.  Revised text has been adapted from MPLS-in-UDP RFC 7510, but 
needs further adaptation for GRE (vs. MPLS).
July 2015 - Scope of deployability discussed in Prague (meeting and 
hallway) - decision is to proceed with 2 applicability scopes - general 
Internet and well-managed Operator Network
ID submitted for Yokohama (probably not final text, but initial stab at 
2 applicability scopes)

DiffServ interconnection classes
New ID presented in Atlanta, IETF-85.
ID presented in Orlando, IETF-86, Mar 2013. Mar 2014, intended scope 
unclear at IETF London Adoption call to be considered, but scope needs 
to be first refined and a revised draft is necessary to avoid 
implications of broader applicability.

this, but a revised draft is needed first.
WG adoption call completed 2014-12-01.
March 2015: Draft got waylaid by a strong request to include a Scavenger 
class.

for Yokohama. Expected response to "Scavenger class" topic is "Send Draft!"
