In any case, the GMAC part is much the same as mvneta, and I think that code should be shared rather than writing new versions of it. There are some subtle differences between neta, pp2.1 and pp2.2, but it's entirely doable (I have an implementation here as I wasn't going to duplicate this code for my phylink conversion.) -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
