Hashing on IP header is not part of any IETF standard, and I am not sure all future IETF
standards should be based on supporting non-standard proprietary implementations. if one likes
to still hash IP header, then he could define a proper protocol mux header and use it all the time.

Tunnel Label - PW label - IPV4/6 explicit null. And hash only up to 2nd label.

Also egress could identify the flow from bottom label.
