One more trivial note:

This bit would be better as:

	if (status_change) {
		if (phydev->link)
			netdev_info(dev, "link UP - %d/%s\n",
				    phydev->speed,
				    phydev->duplex == DUPLEX_FULL
				    ? "full" : "half");
		else
			netdev_info(dev, "link DOWN\n");
	}

so there's no possible interleaving by other
thread messages.
