Continuing my quirky setup on RPi R2 Pro. Spent $20 on a Mini PCIe to PCIe 1 lane + USB 2.0 riser card. Spent $50 on a used AQC113CS card…
Without further due, see the results

Going to fit an ASMedia 2812 PCIe switch with two AQC113CS and see the ip forwarding performance.
@frank-w ASMedia 2812 does not seem to be recognized by your kernel, I am wondering what new drivers need to be included like pcieport?
