+vhost PMD Xstats test plan
+============================
Description
===========
@@ -11,280 +11,335 @@ Description
This test plan will cover the basic vhost pmd xstats test with with 10 tx/rx paths. Includes mergeable, non-mergeable, vectorized_rx,
inorder mergeable, inorder non-mergeable, virtio 1.1 mergeable, virtio 1.1 non-mergeable，virtio 1.1 inorder
mergeable, virtio 1.1 inorder non-mergeable, virtio1.1 vectorized path, also cover stability cases.
+From DPDK 22.07, vhost support per-virtqueue statistics, Per-virtqueue statistics collection will be enabled when the flag "RTE_VHOST_USER_NET_STATS_ENABLE" is set. It is disabled by default.
Note IXIA or Scapy packes includes 4 CRC bytes and vhost side will remove the CRC when receive packests.
-Test flow
+Prerequisites
+=============
+
+Topology
+---------
+
+ Test flow:Traffic Generator --> NIC --> Vhost --> Virtio--> Vhost --> NIC --> Traffic Generator
+
+Hardware
+--------
+ Supportted NICs: ALL
+
+Software
+--------
+
+ Scapy: http://www.secdev.org/projects/scapy/
+
+General set up
+--------------
+1. Compile DPDK::
+
+ # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static <dpdk build dir>
+ # ninja -C <dpdk build dir> -j 110
+ For example：
+ CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc
+ ninja -C x86_64-native-linuxapp-gcc -j 110
+
+2. Get the PCI device ID of DUT, for example, 0000:18:00.0 is PCI device ID::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+ Network devices using kernel driver
+ ===================================
+ 0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+
+Test case
=========
-TG --> NIC --> Vhost --> Virtio--> Vhost --> NIC --> TG
+Common steps
+------------
+
+1. Bind 1 NIC port to vfio-pci::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
+ For example::
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:18.0
-Test Case 1: xstats test with packed ring mergeable path
-========================================================
+2. Check the statistic type and number in each queue is correct.
+ For example: send 1000 packets with 1028B size(includes 4 CRC bytes) with different destination IP to two queues, the total statistic number of tx_q0_size_1024_to_1518_packets and tx_q1_size_1024_to_1518_packets should be 1000, the statistics about the rx direction is the same.
+ Send 1000 packets with ucast type with different destination IP to two queues, the total number of tx_q0_unicast_packets and tx_q1_unicast_packets should both be 1000, the statistics about the rx direction is the same.
-1. Bind one port to vfio-pci, then launch vhost by below command::
+
