I am using 10G Intel card. Looking at product document it says 10Base-KR is supported. Basically i have connected 10G to xilinx development board using SFI interface and need to validate xilinx 10G-Base-KR IP. How to enable base-kr in intel NIC?

[RPand8]

Enabling autoneg using ethtool is throwing error- -EINVAL

sudo ethtool -s ens4 speed 10000 duplex full advertise 0x1000 autoneg on

My requirement is to enable 10G-Base-KR in 82599ES 10-Gigabit SFI/SFP+ Intel NIC.

Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Hello RPand8, Thank you for posting in Intel Ethernet Communities. To further check this issue, please provide the following details: 1. What is your OS? 2. What is the driver version installed? 3. Please provide the error in ethool. If you have questions, please let us know. Best regards, Michael L. Intel Customer Support Under Contract to Intel Corporation

Thanks for the response.

My OS is: Linux radheys41 4.4.0-93-generic #116-Ubuntu SMP Fri Aug 11 21:17:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I upgraded the driver to ixgbe-5.5.5.

Adding print in ixgbe_set_settings shows that we are returning EINVAL when autoneg is enabled.

if ((ecmd->autoneg == AUTONEG_ENABLE) ||

          (ecmd->advertising != ADVERTISED_10000baseT_Full) ||

          (speed + ecmd->duplex != SPEED_10000 + DUPLEX_FULL)){

            printk(KERN_ERR "Set link invalid \n");

            return -EINVAL;

        }

    }

Thanks,

Radhey
