Commit Message

Kory Maincent June 12, 2024, 3:04 p.m. UTC 
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.
