Is this direct MAC to MAC without a PHY in the middle? And RGMII?

500ps seems odd. It is normally 1000ps. And you need to specify a
delay for both Rx and Tx. I could understand

&emac {
	allwinner,tx-delay-ps = <500>;
	allwinner,rx-delay-ps = <500>;
};

then each end adds 1/2 the delay on both Rx and Tx.
