278. vm2vm vhost-user/virtio-user test plan¶
278.1. Description¶
This test plan includes split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test, and packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path test.
