Yes, the hardware does seem to be different from what you describe
but I think the conversion is right. I tested this with ptp4l in a
back-to-back configuration and observed convergence of the master
offset to ~0. Without this code, the offset keeps increasing.

Okay, thanks, just asking.

It appears that this works just like the IGB. The register value is a
binary fraction of the increment value, and not an addend as I
assumed.

Thanks,
