I do not see any "MUST NOTs" in RFC2460, nor any dire consequences for
allowing a tunnel ingress to fragment atomic fragments. So, if we update
the final paragraph of Section 5 of RFC2460 we should be good to go.
On any link that cannot convey a 1280-octet
packet in one piece, link-specific fragmentation and reassembly must
be provided at a layer below IPv6.
also:
(Note: unlike
IPv4, fragmentation in IPv6 is performed only by source nodes, not by
routers along a packet's delivery path -- see section 5.)
So you're talking about updating RFC2460 to allow on-path fragmentation
of source fragments. I disagree with that, for the same reasons it was
omitted from IPv6 in the first place.
