Small addendum: RFC 3542 specify a socket option (11.2.) called IPV6_DONTFRAG,
maybe this is the option you are searching for:
This specification defines a mechanism to turn off the automatic
inserting of a fragment header for UDP and raw sockets. This
can be
enabled using the IPV6_DONTFRAG socket option.
Linux does *not* implement this option. ;-)
Cheers, Hagen
