Hi Uwe

The convectional meaning of phy-mode 'rgmii' is that the PCB provides
the 2ns delay. Here you are abusing the

> +	txc-skew-ps = <1860>;
> +	rxc-skew-ps = <1680>;

To add these delays.

Please test without these two lines, and change phy-mode to
'rgmii-id'. 1680 is rather low, so it might not work. Look for CRC
errors for received packets.
