Thanks for the revisions. Following up on my previous tsvart review, there is one remaining nit from previous transport reviews: - Section 5.3, the list "When doing ITR/PITR encapsulation", third item needs a citation fix: OLD: The 'Explicit Congestion Notification' (ECN) field (bits 6 and 7 of the IPv6 'Traffic Class' field) requires special treatment in order to avoid discarding indications of congestion [RFC3168]. NEW: The 'Explicit Congestion Notification' (ECN) field (bits 6 and 7 of the IPv6 'Traffic Class' field) requires special treatment in order to avoid discarding indications of congestion [RFC6040]. Thanks, cheers, Brian
