Temporary implementation to let virtio operate in non-vec mode for archs which doesn't support _ssse_ cpuflag. todo: 1) Move virtio_recv_pkts_vec() implementation to drivers/virtio/virtio_vec_<arch>.h file. 2) Remove use_simple_rxtx flag, so that virtio/virtio_vec_<arch>.h files to provide vectored/non-vectored rx/tx apis. Fixes:fc3d66212f("virtio: add vector Rx") Fixes:c121c8d6d3("virtio: add simple Tx") Fixes:8d8393fb18("virtio: pick simple Rx/Tx") Signed-off-by: Santosh Shukla <sshukla@mvista.com> Acked-by: Yuanhan Liu <yuanhan.liu@linux.intel.com>
