Humm, i would prefer error counts to be more correct than anything else. When debugging issues, you generally don't care how many packets worked. It is how many failed you are interesting, and how that number of failures increases. So long as these counters are still in ethtool -S, i guess it does not matter. That i do trust to be accurate, and probably consistent across the counters it returns. Andrew
