Hi!

If you account for the Frame Check Sequence when computing bandwidth
stats, it's only fair that you count the preamble and inter-packet gap
as well.  Suggested patch attached.
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 :)
