Are you sure they are 10GBASE-KR, and not 10GBASE-R ? Please send me the contents of MMD 31 register 0xf001. Also knowing MMD 1 registers 2 and 3 would be useful to confirm exactly which version of the PHY has been used. Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
