Speed has nothing to do with frame size.  The 1500 byte limitation is 
more a function of the CRC algorithm.  (Oh, the initial frame size was 
selected for 3-mbit Ethernet so that collision mitigation was reasonable.)

Think about jumbo frames (9000 bytes) and their robust error detection. 
 Research is being done in even larger frames, because the rule is that 
as your transmission rate increases, you should increase the frame size 
and use a FRC algorithm that detects all one-bit errors and most two-bit 
errors, at least.
