'no link' here, so please check your magnetics and RJ-45 connector.

KSZ9031 connects to ethernet MAC with two busses: RGMII and MDIO.
You can read PHY registers, so it seems your MDIO bus works fine,
but there is no warranty that your RGMII link actually works.

Sorry, I have not noted this hardware detail for my board.
Mostly I work as a software developer.
