bnx2: Add prefetches to rx path. Add prefetches of the skb and the next rx descriptor to speed up rx path. Use prefetchw() for the skb [suggested by Eric Dumazet]. The rx descriptor is in skb->data which is mapped for streaming mode DMA. Eric Dumazet pointed out that we should not prefetch the data before dma_sync. So we prefetch only if dma_sync is no_op on the system. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
