This patch updates 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.
