Good evening from Greece!
Ihave a debian system running on kernel 2.6 and a quad card with Digital
21140-AE chips. eth0 and eth2 connect to two lans over full-duplex
capable switches and eth1 connects to my adsl-router (full duplex
capable - I use pppoe, if this info is necessary). I don't know the
brand of the quad ethernet card. Following is the output of lspci, if it
is of any help:

My problem is that all ports are working in half duplex mode..

=====================>8====================================
The problem is: why does the card work in half duplex mode? Why can't I
force it into full-duplex?
I am a linux beginner, so please excuse if I am missing something
obvious.. ;-/ Also excuse my very long message - I just wanted to give
enough info..
Any help would be deeply appreciated..
Basilis (aka tsapi)
