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+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@@ -37,30 +48,30 @@ Topology\n \n Software\n --------\n-    Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n+    qemu: https://download.qemu.org/qemu-7.1.0.tar.xz\n \n General set up\n --------------\n 1.
