ETH3 Interrupts(calc'd from below): 1479968
ETH2 Interrupts: 261543
Packets RX'd on ETH3: 3892720
Packets dropped on RX on ETH3: 10305
This equates to about a 0.26% drop rate. W/ 256 packet RX ring size I see
about a 0.42% drop rate.
This is using both the newest Intel driver w/ your patch and an increased ring
size of 2048.
