Has anyone done this > previously? Sure. It's done all the time in embedded devices that include an Ethernet switch. One port on the switch has a "reverse" MII interface that connects directly the the microcontroller's MII interface. >If so, can you hook me up with a link to a repo/sampleconfig, where >this was done? Not really, all the examples I know of are proprietary. Just take out whatever code you have that's trying to talk to a PHY, then configure the microcontroller's MAC to 100M Full-Duplex (or whatever you want for the link), and you're done. -- Grant Edwards grant.b.edwards Yow!
