Unclaimed Network Adapter

[Jürgen Van Meerhaeghe]

Hi,

I'm facing the issue that one of my network cards remains unclaimed.
Since it is a dual NIC card I think it its not a driver issue?

I'm not sure I know what that output is/means... is it from 'lshw'? So
both network interfaces don't show up in "/sys/class/net/" for that
Intel dual-port NIC? Only one port is usable as a Linux Ethernet
interface?

Hi Marc,

Output is indeed from lshw.

It is a dual nic card, but indeed only one is showing up in /sys/class/net

[root@esos03 ~]# cat /sys/class/net/
bonding_masters  enp2s0f0/        lo/
enp131s0f0/      enp2s0f1/        sit0/

Any interesting messages in the kernel log ('dmesg' output)? Perhaps
something is failing in the driver initialization? Or if the NIC has
an option ROM setup screen accessible at boot, might be interesting to
see if you can change/reset anything there.
