I also tried using ethtool -S, but it seems those counters are the same. Is there any way to get the actual rx/tx packet count on the wire? Also, for the rx/tx bytes, I assume that isn't counting the protocol headers for the physical pkts that have been merged into a single LRO packet. Is there any way to get the wire stats for bytes as well? Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
