    This patch enables user to unload netback module, which is useful when user
    wants to upgrade to a newer netback module without rebooting the host.
    
    Netfront cannot handle netback removal event. As we cannot fix all possible
    frontends we add module get / put along with vif get / put to avoid
    mis-unloading of netback. To unload netback module, user needs to shutdown all
    VMs or migrate them to another host or unplug all vifs before hand.
