> Update the driver code so that we do bulk updates of the page reference
> count instead of just incrementing it by one reference at a time.  The
> advantage to doing this is that we cut down on atomic operations and
> this in turn should give us a slight improvement in cycles per packet.
> In addition if we eventually move this over to using build_skb the gains
> will be more noticeable.
