I haven't tracked down any bug related information with this ethernet controller, but in either case, another resource for getting ethernet setup in Linux running on an 8176 controller is through a Linux forum, as the 8176 is an Intel compatible PC in a different form factor.
The ethernet chipset on the 8176 controller is the Intel 8255x.  For reference, I have gotten the generic 8255x driver to work under Windows, so theoretically, if you can find a generic Linux drive of the same type, it should work.
Best of luck,
