This test plan test +virtio event idx interrupt with cbdma enabled. Also need cover driver reload test. + +..Note: +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. +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. +3.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd. + +Test flow +========= + +TG --> NIC --> Vhost-user --> Virtio-net + +Test Case1: Split ring virtio-pci driver reload test with CBDMA enabled +======================================================================= + +1.
