0.3% dropped packets is a bit unusual for a NIC running against a switch; it would be quite normal for a hub. However, Linux tends to also count various things like unknown VLAN tags, unknown protocols (ie, IPv6 traffic on an IPv4-only host), etc as dropped RX packets. Supposedly ethtool -S helps distinguish between actual interface errors and traffic that your machine chooses to drop. Regards, -- -Chuck
