We had long discussion on that before..:-) Yes, IPv6CS (RFC5121) comes from
16ng WG. And EthernetCS is too. Prebably, the consensus you mentioned above
means which CS is a mandatory or optional for IPv6 implementation or
both. Well, 16ng WG just leaves them to the business choice in WiMAX
networks since that is beyond scope of 16ng. As of today, obviously mobile
biz wants to implement IPv6CS only, and wired biz (looks like DSL) wants to
implemt EthernetCS. But, no one knows what happens tomorrow in WiMAX
networks.
