Tushar,
ethtool -S eth0 shows that my 440000 packets (plus 11 other non test packets)
were transmitted with no errors on the transmitter. On the receive system,
only 439989 packets were received and no errors or drops are recorded.
I have included the full before and after ethtool output below.
Thanks,
Joe
