Log: MFC: r245923 - Check the return value of taskqueue_start_threads(). - At least the Saturn chips of 501-6738 cards need a delay after freezing the external GMII pins before the internal PHY is accessible again. So wait a bit after (un)freezing these. Also don't touch the other bits of that configuration register. [1] - Take advantage of nitems().
