[U-Boot-Users] PCI express NIC for testing?

Hello,

I'm looking for a PCIe card, preferably a NIC, to test PCIe under U-Boot. I have realized, that the E1000 driver of U-Boot does not have support for PCIe cards. It actually lags behind the Linux driver a lot and porting seems to require substantial effort (different SPD EEPROM, PCIe, etc.). Are there other choices?

TIA.

Wolfgang.
