I found measurement results on this website:

Interesting. Did you post on the v6 lists as well?
Just on ipv6-tech...@listserv.internetnz.net.nz
Feel free to forward on to other lists if you think its useful.

That's the frag6 ipfw iusse, right? Well actually 3 issues. I have this
is open in my other window today after having stared at it for too long.
BTW. does anyone have any idea what kind of systems generate these packets?
Does anyone have packet dumps of them? A couple of people would be
curious to have/see that.
In terms of systems that will respond to a PTB by sending IPv6 fragments
rather than sending smaller TCP packets:

(I can go on further if you want)
If I had to guess at what OS sends these packets I'd guess netbsd or
openbsd but I've never looked. To reproduce above, use

Use -M 1480, that will cause the last fragment to be small and trigger
one of the bugs in the PR.
In terms of systems that will respond to a PTB with nhmtu < 1280, it
seems most follow the advice in RFC2460 and send packets with a
fragmentation header without fragmenting the packet. Use -M 576 with
your scamper command line.
