DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd. In this patch,\n+   we enable asynchronous data path for vhostpmd. Asynchronous data path is enabled per tx/rx queue, and users need to specify\n+   the DMA device used by the tx/rx queue. Each tx/rx queue only supports to use one DMA device (This is limited by the\n+   implementation of vhostpmd), but one DMA device can be shared among multiple tx/rx queues of different vhost PMD ports.\n \n-For more about dpdk-testpmd sample, please refer to the DPDK docments:\n-https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html\n-For virtio-user vdev parameter, you can refer to the DPDK docments:\n-https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.\n+   Two PMD parameters are added:\n+   - dmas:\tspecify the used DMA device for a tx/rx queue.(Default: no queues enable asynchronous data path)\n+   - dma-ring-size: DMA ring size.(Default: 4096).\n+\n+   Here is an example:\n+   --vdev 'eth_vhost0,iface=./s0,dmas=[txq0@0000:00.01.0;rxq0@0000:00.01.1],dma-ring-size=2048'\n+\n+   For more about dpdk-testpmd sample, please refer to the DPDK docments:\n+   https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html\n+   For virtio-user vdev parameter, you can refer to the DPDK docments:\n+   https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.\n \n Prerequisites\n =============\n \n Software\n --------\n-Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n+   Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n+   iperf\n+   qemu: https://download.qemu.org/qemu-7.1.0.tar.xz\n \n General set up\n --------------\n@@ -46,9 +58,9 @@ General set up\n \n \t# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static <dpdk build dir>\n \t# ninja -C <dpdk build dir> -j 110\n-\tFor example:\n-\tCC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc\n-\tninja -C x86_64-native-linuxapp-gcc -j 110\n+    For example:\n+    CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc\n+    ninja -C x86_64-native-linuxapp-gcc -j 110\n \n 3.
