Following edits have been made to the draft

- Added details on IFA header as a layer 3 extension header

- Packet format for IP AH/ESP/WESP

- Packet format with IPv6 extensions (needed for 5G deployment)

- Concept of metadata fragmentation function (needed for 5G deployment)

                - to handle very large number of hops in a flow path

                - to handle any limitation for deleting the metadata stack on the terminating node

- Postcard mechanism as a degenerate usecase of fragmentation function.

                - each node generates IFA report aka postcard as a fragment.

Regards,

-Jai
