Two thought of dubious value:

 1. Have you looked a the SPI bus? That is fast enough to support
ethernet interfaces. This could be connected between two boards then the
onboard ethernet used to connect to the two networks.

2. The Beagle Bone Green comes with four USB ports and the Samsung
Arktik various numbers of USB ports depending on the model.
