> When netvsc_resume() is called, the mlx5 VF NIC has not been resumed yet,
> so in the future the host might sliently fail the call netvsc_vf_changed()
> -> netvsc_switch_datapath() there, even if the call works now.
> Call netvsc_vf_changed() in the NETDEV_CHANGE event handler: at that time
> the mlx5 VF NIC has been resumed.
