During successful probe, igc logs this:
[ 5.133667] igc 0000:01:00.0 (unnamed net_device) (uninitialized): PHC added
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The reason is that igc_ptp_init() is called very early, even before
register_netdev() has been called. So the netdev_info() call works
on a partially uninitialized netdev.
Fix this by calling igc_ptp_init() after register_netdev(), right
after the media autosense check, just as in igb. Add a comment,
just as in igb.
Now the log message is fine:
[ 5.200987] igc 0000:01:00.0 eth0: PHC added
