VIRTIO_F_ORDER_PLATFORM is required to use proper memory barriers in case of HW vhost implementations like vDPA. DMA barriers (rte_cio_*) are sufficent for that purpose. Previously known as VIRTIO_F_IO_BARRIER. Signed-off-by: Ilya Maximets <i.maximets@samsung.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com> Acked-by: Michael S. Tsirkin <mst@redhat.com>
