MTU is different for different kinds of networks. On Ethernet (up to
100Mbit speed) it is 1500 bytes). ADSL may use different values,
depending on what it uses for encapsulation (but I do not know the exact
values).

To make a real good test, you'd need to setup two MiNT boxes, connect
them with Ethernet and try to transfer data between them. Try different
MTUs on both machines. If it will work OK - MiNT is not to blame. If it
is not OK, MiNT has some bugs (well, not MiNT exactly, just Ethernet
driver).
