      Description

      Rarely we are observing binding issue during setting virtio-pc driver for TG interfaces (run as part of Test or Suite setup):

      We tried to fix it by forcing pci inerfaces rescan but it didn't help. The problem is that even the port is already binded to the driver the corresponding information is not returned (see red highlighted text) so current driver is considered to be None and script is trying to bind the interface to required driver (yellow highlighted text).

       

      Full log file is attached.
