Re:Call for adoption: <draft-krishnan-6man-sids-00>

Hi all,

I support WG adoption of this draft.

At the same time, I've noticed that RFC8200's rule on how to compute upper-layer checksum might be updated by the introduction of compressed SIDs.
In order to compute checksum for upper-layer protocol, section 8.1 of RFC 8200 defines the TCP and UDP "pseudo-header" for IPv6, with respect to the Destination Address of the "pseudo-header", it says
"      o  If the IPv6 packet contains a Routing header, the Destination
         Address used in the pseudo-header is that of the final
         destination.  At the originating node, that address will be in
         the last element of the Routing header; at the recipient(s),
         that address will be in the Destination Address field of the
         IPv6 header.
"
In one case of compressed SIDs, a Routing header isn't there and the IPv6 destination address isn't that of the final destination; In the other case of compressed SIDs, a Routing header is there and the destination address of the final destination isn't in the last element of the Routing header. For both cases section 8.1 of RFC 8200 needs update.

IMO the checksum issue needs to be recorded somewhere and this draft seems the right place, or I can initiate a new draft on this if it's preferred.

Best Regards,
Xiao Min
