Which interface mode is being used, and what is the MAC connected to? "Reversed" seems to imply that _this_ end is acting as a PHY rather than the MAC in the link, so I think a bit more information (the above) is needed to ensure that this is the correct solution. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
