Hi, I had raised this earlier in December 2005 http://www1.ietf.org/mail-archive/web/ipv6/current/msg06020.html .
The definition of IPv6 fragment is not clear. Infact different protocols assume it differently, example are IPsec and SIIT. I do not have implementations to play with, however I feel we need to close this issue along with other related issues, like tiny fragments. The discussion there was: " Vishwas Manral wrote: I have a doubt regarding the fragment header. Why do we need the M flag in the "fragment header" at all for IPv6? Having the fragment header itself would tell it's a fragment and would distinguish between the first fragment and a non-fragment. In IPv4 we did not have a fragment header, so the M flag was logical to have for distinguishing the first and a non fragment. That said; how should the case where we have the fragment header and both the Fragment Offset and the M flag is 0 be treated?"
