I'm unfortunately not up to speed yet on what has been tried so far, but I do plan to start prototyping the idea soon and I'll probably find your patches then. My basic idea is to interface a Raspberry Pi-like board to a dumb "switch evaluation board" which has only the Ethernet ports and the SPI/whatever control interface exposed. The DSA CPU/master port combo in this case would go through a Cat5 cable, which is not going to pan out very well currently because both the RPi-side PHY and the switch board-side PHY need some massaging from their respective drivers. Both PHYs are C22. A rough idea of what I'm actually planning to do at: https://www.spinics.net/lists/netdev/msg569087.html -Vladimir
