Enable the controller, hand it the ethernet pins and point it at the PHY. RGMII needs a delay on each of its two clocks, and on this board both come from inside the chips, not from the board traces. The PHY adds the one on receive. Its transmit delay does not work here, so the controller adds that one. The PHY interrupt output is wired to GPIOH_6, so link changes are reported instead of polled. The PHY reset is an RC network on the board, not a SoC pin, so there is no reset line to describe.
