-Verify that the increase in RX-bytes and RX-packets is as-expected, and no other information changed.
+Functional Tests of xstats Checks
+==================================
+
+Testing the support of xstatus Checks in Poll Mode Drivers consists of
+configuring the gathering the initial status of a port, sending some
+packets to that port, and checking the xstatus of the port.
+This case will compare the initial xstatus and the new xstatus,
+and compare the xstats and stats result.
+The fields checked are RX-packets and TX-packets of each queue stats,
+RX-packets, RX-bytes, TX-packets and TX-bytes of each port stats,
+rx_good_packets and rx_good_bytes of each port xstats,
+tx_good_packets and tx_good_bytes of each port xstats,
+rx_qx_packets, rx_qx_bytes, tx_qx_packets and tx_qx_bytes of each port xstats.
+
+Test Case: PF xstatus Checks
+============================
+1. Bind two PF ports to pmd driver::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci device_bus_id0 device_bus_id1
+
+2. Launch testpmd and enable rss::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -- -i --rxq=4 --txq=4
+    testpmd> port config all rss all
+    testpmd> set fwd mac
+
+3. show the xstats before packet forwarding, all the value are 0.
+4. Start forward and send 100 packets with random src IP address,
+   then stop forward.
+
+5. Check stats and xstats::
+
+  testpmd> stop
+  Telling cores to stop...
+  Waiting for lcores to finish...

+Test Case: VF xstats Checks
+============================
+1. Create one VF port on a kernel PF, then bind the VF to pmd driver::
+
+    echo 1 > /sys/bus/pci/devices/device_bus_id/sriov_numvfs
+    ./usertools/dpdk-devbind.py -s
+    ./usertools/dpdk-devbind.py -b vfio-pci vf_bus_id
+
+2. Launch testpmd on the VF and enable RSS::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -- -i --rxq=4 --txq=4
+    testpmd> port config all rss all
+    testpmd> set fwd mac
+
+3. Then run the same steps of PF xstats Checks, get same result.
+note: because one port forwarding packets, so check rx and tx both in port 0.
