Hi Jakub, Serge,
If agreed, this commit can go in. I can submit another patch with the refactoring suggested by Serge.
Again, thanks Serge for the prompt response. Regarding the below point in your earlier response,

This is a little confusing... I referred databooks for DW QoS Eth v5.30a and DW XGMAC v3.10a. In both this is mentioned as "The value of PTP Clock period multiplied by 9 in nanoseconds".
