Subject: [PATCH net-next v3 0/2] amd-xgbe: add hardware PTP timestamping

Remove the hwptp abstraction and associated callbacks from the
struct xgbe_hw_if {} and move them to separate file after cleanup.

Adds complete support for hardware-based PTP (IEEE 1588)
timestamping to the AMD XGBE driver.

Signed-off-by: Raju Rangoju <Raju.Rangoju@....com>

Changes since v2:
- add a new patch to clean up the existing abstraction and move to seperate file
- clean up the support patch as per review comments
