ixgbevf: update code to better handle incrementing page count
Based on commit bd4171a5d4c2
("igb: update code to better handle incrementing page count")
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.
