If that is what "-nojumbo" was supposed to do, what is it called when you 
stuff (or do not stuff) serveral (small) rx-packets into one UDP packet?

All this stuff confuses me and a lot of network equipment and I allway
try to turn it OFF. Working MTU discovery for the whole path would be
nice. Can we do better than the usual ICMP based one that seldom works
because of firewalls NAT and the like?
