Honestly, it would be much simpler to just connect the two board together via an ethernet cross over cable if possible. Or, if you have other ideas for the erthernet ports, and you're comm traffic is light, You could purchase a 3v3 TTL serial to USB cable, and communicate between the two over serial.
