You seem to be avoiding that here. If the PHY is not functioning properly after the ->resume() triggered reset, fix that instead. I'm not applying this patch, it doesn't look the right thing to do at all. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

* with this patch, if the connection if active before suspend, it will be active after resume. * before this patch, it was necessary to close the interface and reopen it to recover the connection.
