Ok, no rush: linux kernel can have some of its components compiled as

Even worse. Kudzu blew the identification. It is really a "3com940 1000base?". STill, ethtool -s eth0 duplex half doesn't work. So, back to your idea we go...




you will see which modules are currently loaded for your kernel. Modules
configuration stays on /etc/modules.conf (man is your friend). Modules
usually can tell how to configure them with the 'modinfo' command I
showed above. This means that if you run

modinfo [module-name]

you will be presented some basic description and the allowed parameters.
Combining all the above info, you can infer what this entry on my
/etc/modules.conf does:



OK, but as it turns out, there are no modules for this card. I do have a second card in there, a 3com501, and Kudzu won't even recognize it. I believe there's a big bug to swat for that one in bugzilla. Anyway...




options nvnet duplex=2 > (answer: it is saying that nvnet modules should be loaded with
param 'duplex' set to 2, which means full-duplex on my case).


TIP: do a 'man modprobe'.



Yep. Unfortunately, I don't have any modules for it, and I don't know where to get one.


There is a module loaded for it, or it would not work.

Post the output of lsmod and we can help identify it for you.
