I just updated the Intel Drivers to the latest on source-forge(5.6.10.1). I
now see lower CPU usage but I am still dropping.
During a 60 second window the machine received 5,110,164 packets and dropped
20461 or roughly 0.4% packet loss.
cat /proc/net/softnet_stat

It has been at 150dc67c for a while now. So while I am dropping at the card,
I am not dropping in the stack.
