I can see 3 supported Ethernet chipsets mentioned on the official list of supported hardware:

- RTL8029: 10MbE
- RTL8139: 100MbE
- RTL8168: 1000MbE (GbE)

Unless you already have one of those at hand, it should be obvious which one to obtain :-)


Edit: Of course, as your Mac has no PCI(-X) but only PCIe, the other two chipsets are irrelevant for this reason alone as there simply are no PCIe cards using them.
