This change is required to have the interface name for virtio interfaces.
When we execute the status command the for virtio inerfaces we get
Sample output without the change:
0000:00:04.0 'Virtio network device' if= drv=virtio-pci unused=virtio_pci,igb_uio
Though for other drivers this works.
Sample output with the change:
0000:00:04.0 'Virtio network device' if=eth0 drv=virtio-pci unused=virtio_pci,igb_uio
