It seemed to come down to either a problems with mii-tool and ethtool or a problem with the mii interface in the NIC driver. I put my money on the driver as both mii-tool and ethtool work for myself and others. However, I think this same advice should pertain to you both. Just because the software interface is returning incorrect information doesn't mean that the mii hardware isn't doing it's job. Link negotiation happens at the hardware level even without the presence of a driver. WOL cards maintain link even when the machines they are in are powered off. Software, if properly implemented, can allow you to query and sometimes even set mii parameters, but usually this is best left to the hardware. Does your NIC have both link and speed leds? If so, what speed do they indicate? I would be willing to be they show 100Mbps. In this case, I would trust what the hardware is telling you and not what the software is telling you. Mind you, I don't think it's good that mii-tool and ethtool are reporting faulty information, but I do think that if you dig deep enough, you're going to find that the problem is with the NIC and the available driver. You might check the manufacturers page to see if there are any known problems with linux in general and fedora in particular. While you're there, look into the manufacturers policy on linux support and also their usage of hardware tweaks. Not all OEM chipsets are created equal. BTW, what NIC are you using?
