PHC support for NanoPi R76S

[muetzekoeln]

NanoPi R76S is supposed to have PHC hardware timestamp support with both ethernet interfaces. Unfortunately ethtool -T returns no hardware support. Would be great if PHC could be enabled in this nice box.

From a quick research it seems mainline driver does not support this. You need to install out of band driver from realtek

yes. I tried r8125-9.016.01 but with mixed results. Ethernet addresses could not be read by the new driver. And PHC support was no longer shown after reboot.
