Ethernet Switch on PCB

I'm currently designing a board that is using a SoC to get a first design iteration off the ground.
The SoC is a SAMA5D27-SOM1 from Microchip.

Part of the requirements is to have at minimum dual ethernet connectivity with management to keep two separate networks. I'm learning as I go, so my terminology may be wrong.

The SAMA5D27-SOM1 has an ethernet phy with the ethernet differential outputs. There are no (from what I know so far) MII or other interfaces that are easily usable to achieve this available on the SoC. I have looked at various switches, especially the Microchip KSZ8794CNX. These all require some form of interface, rather than taking the ethernet signals in.

Am I missing something simple here?!
