@@ -42,10 +42,13 @@ This test plan test several features in VM2VM topo:
in the UDP/IP stack with vm2vm split ring and packed ring vhost-user/virtio-net mergeable path.
2. Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
+3. Check Vhost tx offload function by verifying the TSO/cksum in the TCP/IP stack with vm2vm split ring and
+packed ring vhost-user/virtio-net mergeable path with CBDMA channel.
3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring when vhost enqueue operation with multi-CBDMA channels.
Note:
1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version > LTS 4.2.1, dut to old qemu exist reconnect issue when multi-queues test.
+3.For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.

===========
This test plan test several features in VM2VM topo:
-1. Check Vhost tx offload (TSO and UFO) function by verifing the TSO/cksum in the TCP/IP stack and UFO/cksum
+1. Check Vhost tx offload (TSO and UFO) function by verifying the TSO/cksum in the TCP/IP stack and UFO/cksum
in the UDP/IP stack with vm2vm split ring and packed ring vhost-user/virtio-net mergeable path.
2. Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
+3. Check Vhost tx offload function by verifying the TSO/cksum in the TCP/IP stack with vm2vm split ring and
+packed ring vhost-user/virtio-net mergeable path with CBDMA channel.
3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring when vhost enqueue operation with multi-CBDMA channels.
Note:
1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version > LTS 4.2.1, dut to old qemu exist reconnect issue when multi-queues test.
+3.For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.

===========
This test plan test several features in VM2VM topo:
-1. Check Vhost tx offload (TSO and UFO) function by verifing the TSO/cksum in the TCP/IP stack and UFO/cksum
+1. Check Vhost tx offload (TSO and UFO) function by verifying the TSO/cksum in the TCP/IP stack and UFO/cksum
in the UDP/IP stack with vm2vm split ring and packed ring vhost-user/virtio-net mergeable path.
2. Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
+3. Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and
+packed ring vhost-user/virtio-net mergeable path with CBDMA channel.
3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring when vhost enqueue operation with multi-CBDMA channels.
Note:
1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version > LTS 4.2.1, dut to old qemu exist reconnect issue when multi-queues test.
+3.For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.

in the UDP/IP stack with vm2vm split ring and packed ring vhost-user/virtio-net mergeable path.
2. Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
+3. Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and
+packed ring vhost-user/virtio-net mergeable path with CBDMA channel.
3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring when vhost enqueue operation with multi-CBDMA channels.
Note:
1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version > LTS 4.2.1, dut to old qemu exist reconnect issue when multi-queues test.
+3.For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.
