Wouldn't doing IPv4 fragmentation before translation to IPv6 be logically identical to this other case I mentioned? >> - When a SIIT translator receives an IPv4 fragment, it will translate >> this into one or more IPv6 fragments. I can't see how simply omitting the Fragmentation header in the IPv6 output could work here, as the node receiving those two unfragmented IPv6 packets would see the first one containing a truncated L4 payload, while the second one would be just garbage as it doesn't include a L4 header.
