there are probably tools that do that, but I have none
in mind.
what you can do is send packets with the "DF" bit set, using
large MTUs, and if you get an icmp error caused by
"fragmentation neede but DF set", then you know it's too high...
before I forget: you need raw sockets here...
take a look at Stevens source code for "Unix Network Programming"
on http://www.kohala.com/start/.
