strange.
maybe you have a driver limit in e100, but it should not be as long as it

well, your switch (apart from some switch) suppose that you have 1500 byte of 
mtu.
and all machine in your lan suppose it.
you will have fragmentation your packet, if you are luckie, and maybe 
sometimes you will lose big packets (at least, i did).

ok, that should not be in theory, but in real world it is something like
