Hi Mark,

Yes, also "Fragmentation Option for Generic UDP Encapsulation":

https://datatracker.ietf.org/doc/draft-herbert-gue-fragmentation/

Both are essentially the same concept - hike the fragmentation header
up to the encapsulation layer instead of the IP layer. The idea originally
came from RFC2764.

Thanks - Fred
