[PATCH net-next v15 10/14] net: netdevsim: ptp_mock: Convert to netdev_ptp_clock_register

Kory Maincent
2024-06-12T15:05:08Z

The hardware registration clock for net device is now using
netdev_ptp_clock_register to save the net_device pointer within the PTP
clock xarray. netdevsim is registering its ptp through the mock driver.
It is the only driver using the mock driver to register a ptp clock.
Convert the mock driver to the new API.
