If you mean mega = 1048576, it's impossible since this is faster than 100
Mbps whichever way you count it.
If you mean mega = 1000000, it depends on which way you're counting. The
"speed of light" for TCP, application to application, on 100 Mbps Ethernet
is 100 * 1460/1538 = 94.93 Mbps. This assumes full duplex.
I've measured 94.87 Mbps myself on full duplex 100BaseTX (back to back
with a crossover cable or through a switch). This is close enough to
the "speed of light" that I see no point in trying to improve on it...
