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. I also found and fixed a store forwarding stall from where we were assigning "*new_buff = *old_buff". By breaking it up into individual copies we can avoid this and as a result the performance is slightly improved.
