      What were you trying to do that didn't work?

      Setting the following tuneD configuration: 

      [net]
      channels=combined 4

      might result in a degraded tuneD profile, as it trying to collect info with ethtool on a device that doesn't exist.

      We believe, there is a race condition between the system service responsible for the net devices renaming and the tuned pod which tries to grab the device channels (ethtool -l device). The probability of the bug reproducing increases when we create more VFs.

      This has been reproduced on an SNO with DU configuration

      How reproducible is this bug?:

      Around 50%, on an SNO with DU profile
