- In qsphy_service() for the MII_TICK case don't bother to check whether   the currently selected media is of type IFM_AUTO as auto-negotiation   doesn't need to be kicked anyway. - Don't set MIIF_NOISOLATE so qsphy(4) can be used in configurations   with multiple PHYs. There doesn't seem to be a problem with isolating   QS6612 per se nor in combination with the NICs they're used with. - Use mii_phy_add_media() instead of mii_add_media() so the latter can   be eventually retired. - Take advantage of mii_phy_setmedia().
