a) When an ethernet NIC claims 100Mbps, does this count the preamble and IPG?
b) Or, can send and receive 100Mbps of data by only counting
the ethernet header + payload + CRC?
If b is true, then I definately would not want to see the IPG and preamble
counted. If a is true, then I still don't want it counted, but I would
agree that it is worth considering :)
