[libvirt] [PATCH] conf: Format interface's driver more frequently
There's this <driver/> element under <interface/> which can have
several attributes. However, the driver element is currently formated
only if the driver's name or txmode has been specified. This makes
only a little sense as we parse even partial <driver/>, for instance:
<interface type='user'>
<mac address='52:54:00:e5:48:58'/>
<model type='virtio'/>
<driver ioeventfd='on' event_idx='on' queues='5'/>
</interface>
But such XML would never get formatted back.
