RE: 3c905 problem

[Galappatti, Kishantha]

sounds like your hub and NIC card are mismatching on duplex, i.e. one is set
to half duplex (HDX) and one to full duplex (FDX). You don't need a switch
to fix the problem, you need to set them both to FDX.

Subject: 3c905 problem

Sorry to bother you with a stupid question, but I don't know enough to
understand this.

I moved a machine which has a 3c905 connected to a linksys autosense
10/100 hub.  I set no options on the 3c905 module.

I get millions of dreaded:

What exactly does this mean?  How do I fix it?  I have looked at
Documentation/networking/vortex.txt, but I don't know what this
HDX/FDX means exactly, and how works with a hub or switch.  Would my
problem be fixed by replacing the hub with a "switch"?
