If you have a hardware clock which you can slew, and the ability to take hardware timestamps I am failing to see how you are unable to implement the PHC subsystem calls? I suspect however you are converting the timestamps taken by hardware is incorrect, and we can't help you with that easily. This is the first place I would look for an issue, especially if you can confirm that your software timestamps without the special ethernet driver work as expected.
