 virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed.
 This feature test need cover different rx/tx paths with virtio 1.0 and virtio 1.1, includes split ring mergeable, non-mergeable, inorder mergeable,
 inorder non-mergeable, vector_rx path and packed ring mergeable, non-mergeable, inorder non-mergeable, inorder mergeable, vectorized path.
-Split ring and packed ring test when vhost enqueue operation with multi-CBDMA channels. When DMA devices are bound to vfio driver,
-VA mode is the default and recommended. For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.
