While y'all are looking at MTU (which is an increasingly important topic
as we move into a Gig+ world) I'm wondering what our support is for
https://tools.ietf.org/html/rfc4821 ?? I asked this a while back and
never got an answer.

This method of PMTUD is really important given the massive (stupid)
brokenness of people routinely blocking all of ICMPv4.
