[tulip] DFE-570-TX carrier and frame errors

[Lars Olsson]

Hello,

I have problem with carrier and frame errors
on an quad-port D-Link TFE-570-TX card 
the #2 nic seems to have the most problem i think it's duplex related.
But when i check with mii-diag and tulip-diag i have problem
understanding the output of mii-diag vs. tulip-diag.
For me it look's like mii-diag says 100Mb Full Duplex
and tulip-diag say's Half duplex. Please correct me if i'm wrong.

Kernel is 2.2.19 
module is
