https://issues.redhat.com/browse/OCPBUGS-16085

when trying to set a combined channel using net plugin on a non supported device - an error is thrown without specifying the device name which is not supported.

Please provide the package NVR for which bug is seen:

Openshift 4.11.12 

Red Hat Enterprise Linux CoreOS 411.86.202210201510-0  (and above)

How reproducible:

Always if trying to set a combined channel with tuned's net plugin on a non supported device.

Steps to reproduce

using a tuned profile with:

[net]

channels=combined 8

for example, where non supported devices (running ethtool to change channel count fails)

will results in error log messages without specifying the device name:
2023-05-05T11:44:39.877209503Z 2023-05-05 11:44:39,876 ERROR    tuned.utils.commands: Executing ethtool error: netlink error: requested channel count exceeds maximum (offset 40)
2023-05-05T11:44:39.877209503Z netlink error: Invalid argument

Expected results

Have the failing device name specified when net plugin fails to apply the desired settings.
