Hi. I noticed that my Zotac IONITX-C-U mainboard is only doing
100mbit although the ethernet device is 1000mbit. I know the chip is
a Realtek 8211CL because I looked at the mainboard and got the model
number directly from it. If I plug another box into the same cable,
it auto-negotiates 1000mbit no problem so that rules out a cable
problem.
Any help/suggestions are appreciated!
Not sure what info is needed but I'm using debian testing with drivers
from stable kernel 2.6.38. My kernel config has:
Device Drivers > [*] Network device support:
<*> PHY Device support and infrastructure > <*> Drivers for Realtek PHYs
[*] Ethernet (10 or 100Mbit) > [*] EISA, VLB, PCI and on board
controllers > <*> nForce Ethernet support
