Alan, one thing that came to mind to support long TCP option for plain-mode/TFO something might be required in the base draft. For Ipv6 we need more space and if we design it well we can use it for TCP-AO, etc etc Besides this we are good afais On 19/10/2016, 17:17, "Henderickx, Wim (Nokia - BE)" <wim.henderickx@nokia.com> wrote: I don’t expect changes to the base spec.
