This plan test +vhost DMA operation callbacks for DSA PMD and vhost async data-path in vhost sample. + +--dmas This parameter is used to specify the assigned DMA device of a vhost device. Async vhost-user +net driver will be used if --dmas is set. For example –dmas [txd0@wq0.0,txd1@wq0.1,rxd0@wq0.2,rxd1@wq0.3] +means use DMA channel wq0.0/wq0.2 for vhost device 0 enqueue/dequeue operation and use DMA channel +wq0.1/wq0.3 for vhost device 1 enqueue/dequeue operation. The index of the device corresponds to +the socket file in order, that means vhost device 0 is created through the first socket file, +vhost device 1 is created through the second socket file, and so on. + +For more about vswitch example, please refer to the DPDK docment: +http://doc.dpdk.org/guides/sample_app_ug/vhost.html + +Prerequisites +============= + +Hardware +-------- +Supportted NICs: NIC that supports VMDQ + +Software +-------- +Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz + +General set up +-------------- +1.
