Is the eth0 nic a pci card? If so run lspci. As for the results from
ifconfig, you've got some problems on eth0. Look at the collision count,
16meg? Hmmmm is this connection made to a simple hub or a hub with switch
features? If it's a simple hub, swap it for a switch. If it's a switch,
then you've got some misconfiguration to straighten out. Start with looking
over /var/log/messages for network errors at bootup and during operation.
Good luck.
