I have a few questions related to driver modifications on the Ethernet interface.
Is there a way to remove reliance on the MDIO pins or fake it out in some way? We have a test fixture board with the ports and PHYs, and everything routes through an FPGA, which does not have enough I/O for the MDIO.Thanks in advance,
Intriguing application... just my thoughts/questions

From what I see, MDIO and EMAC are implemented as different Device Abstraction Layers. So, if you have a separate arrangement for PHY interface, then you could have your own abstraction and replace references with MDIO with the references to your interface.

If you do not have an interface for PHY interaction (which in this case is MDIO) how do you get link related details? If you have a way seems you have no problem?
Not very sure of what you need, perhaps more details would help?
Thanks and regards,
