I guess this means that if an ICMP error message is generated then
the chunk of the original packet quoted by the ICMP error should
reflect the e2e flow label?
Using the flow label to validate recieved ICMP error messages is
quite appealing in light of draft-gont-tcpm-icmp-attacks-03. It
could also be used for validating ICMP messages generated by UDP
packets, where sequence numbers are not available but a flow label
could be set.
