Are you aware of a TCP implementation in an OS that shipped within the last decade but doesn't enable IPv4 pMTUd by default?
I am not, but I'd still be vaguely interested in an actual study :-) The last time I tangled with v4 pMTUd it actually was a decade or more ago. At that time wholesale ICMP blocking caused all kinds of problems for clients with a sub-ethernet MTU in their path. If the world has moved on, that seems good :-) Joe
