ixgbevf: add support for DMA_ATTR_SKIP_CPU_SYNC/WEAK_ORDERING
Based on commit 5be5955425c2 ("igb: update driver to make use of DMA_ATTR_SKIP_CPU_SYNC") and commit 7bd175928280 ("igb: Add support for DMA_ATTR_WEAK_ORDERING") Convert the calls to dma_map/unmap_page() to the attributes version and add DMA_ATTR_SKIP_CPU_SYNC/WEAK_ORDERING which should help improve performance on some platforms. Move sync_for_cpu call before we perform a prefetch to avoid invalidating the first 128 bytes of the packet on architectures where that call may invalidate the cache.
