Network Card Error, ipconfig report error on eth0

Hello every one,

I have a RedHat server with 3 network card, two are working fine, but the
other (eth0) is having problems, if I use ipconfig I can see many error
report it.

This problem card (eth0) is equal then the eth1, both has the same driver,
and similar configuration.

This networks are just use it for transmit and receives small plain text, so
the problem card is working but block all files greater then 700b and some
smaller pass but get empty.

I'm looking for differences between the eth0 (bad card) and eth1 (good card)
and I just found one (I don't see IRQ collision), when I check the file
/proc/pci the eth0 (bad card) has after Master Capable. No bursts. and the
eth1 (good card) has Latency: 32, I believe that these is the problem,
because I saw many other configurations and all have Latency: and number,
but I don't found information about what it mean "No bursts" and how change
it to Latency:32.



Any body know some thing about it?

Thank you so much,
