I have just received my new X310 + Intel 82599EB. I cannot ping the device.

  1. If I connect the X310 to the 1Gb ethernet port of my host then everything works fine;
  2. If I connect the X310 to the 10Gb 82599EB with the supplied cable, I cannot ping the device. I have the latest versions of the ixgbe kernel module (4.1.5) and the ethtool utility (4.2).

My kernel version is 3.18.2.

Here is some diagnostic output:

root@blacklist:~# ifconfig eth1
eth1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.10.1  netmask 255.255.255.0  broadcast 192.168.10.255

                               drv probe link
        Link detected: no

What bothers me is the line "Speed: Unkown!"

If I try to manually set the speed, I get an error:

root@blacklist:~# ethtool -s eth1 speed 1000
Cannot set new settings: Invalid argument
  not setting speed
root@blacklist:~#

Any ideas of what am I doing wrong and what to try?

Figured out the problem. I was trying to connect 10Gb port on the host to a 1Gb port on the device. This doesn't work and I didn't know that that.
