--- Comment #3 from Robert Watson <rwatson@FreeBSD.org> ---
A further note on the problem:

A good question is whether the current behaviour actually makes sense: do we
really need to notify all sockets of a change in MTU discovered by one socket
on transmit? Or can we just let the others sockets discover the change on
demand as they next try to transmit?

(I don't take a strong view on the answer, except to point out that it would be
simpler if, as in IPv4, we didn't try to notify all sockets of the event.)
