In principle, GE uses the same frames as normal Ethernet. There are,
however, Jumbo Frames, which go upto 9000-and-a-bit (9014 AFAIR) bytes.
I haven't checked lately, but the problem with jumbo frames was/is that
they weren't standardized. A lot of switches can't/won't handle them,
some will, but only with certain types of cards, etc.
