mini pcie expand gige

I want to expand gige by mini pcie, on my new carrier board. Which model is more appropriate? Best not to change driver.

Long ago I used one of these on Tegra 3 (and tested as working with Jetson TK1):

…I don’t know if those are actually still manufactured though.

The Realtek chip set is what you’d be looking for. That board uses the same driver as the integrated hardware on the JTK1…probably this is true on a TX1 as well, but I don’t know for sure.

Tanks a lot~
