Unfortunately I don't have many other bits of 10G hardware to go replacing things, but I'm a bit at a loss. This is on 7.1rc6 apart from disabling autoneg wasnt too sure what to do. I tried forcing it to 1GB but the other side (linux won't let me):[ 6002.933547] ixgbe: Intel(R) 10 Gigabit PCI Express Network Driver

Any ideas what could be wrong here? It seems everything should be working?$ sudo ethtool -s ens2 speed 1000 duplex full autoneg off
