If you're going to draw diagrams, make sure you do it using a fixed-width font. To me, it looks like the MII Converter is bolted to GMAC and only has one connection, and the GMAC has what seems to be maybe five connections. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
