Can we clarify exactly what you are talking about here. What does "KR port" refer to? What protocol is spoken by this port? Is it 1000BASE-KX (1000BASE-X over backplane)? Does it include 10GBASE-KR? Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
