I think it would be better to maintain default as an error case
for unknown mac_type values. (completely untested!)

	switch (hw->mac_type) {
	case ICE_MAC_E810:
	case ICE_MAC_E830:
	case ICE_MAC_GENERIC_3K_E825:
		return ice_ptp_init_tx(pf, &ptp_port->tx, ptp_port->port_num);
	case ICE_MAC_GENERIC:
		kthread_init_delayed_work(&ptp_port->ov_work,
					  ice_ptp_wait_for_offsets);
		return ice_ptp_init_tx_e82x(pf, &ptp_port->tx,
					    ptp_port->port_num);
	default:
		return -ENODEV;
	}

And update the Return: section in the Kernel doc accordingly.
