This test plan test \n+virtio event idx interrupt with cbdma enabled. Also need cover driver reload test.\n+\n+..Note:\n+1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > 5.1, and packed ring multi-queues not support reconnect in qemu yet.\n+2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version >= 5.2.0, dut to old qemu exist reconnect issue when multi-queues test.\n+3.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd.\n+\n+Test flow\n+=========\n+\n+TG --> NIC --> Vhost-user --> Virtio-net\n+\n+Test Case1: Split ring virtio-pci driver reload test with CBDMA enabled\n+=======================================================================\n+\n+1.
