+===========================
+VF Shutdown API Queue Tests
+===========================
+
+This tests for Shutdown API feature can be run on linux userspace. It
+will check if NIC vf port can be stopped and restarted without exiting the
+application process. Furthermore, it will check if it can reconfigure
+new configurations for a port after the port is stopped, and if it is
+able to restart with those new configurations. It is based on testpmd
+application.
+
+The test is performed by running the testpmd application and using a
+traffic generator. Port/queue configurations can be set interactively,
+and still be set at the command line when launching the application in
+order to be compatible with previous test framework.
+
+Prerequisites
+-------------
+
+Assume port A and B are connected to the remote ports, e.g. packet generator.
+Get the pci device id of DUT, for example::
+
+ ./usertools/dpdk-devbind.py -s
+
+ 0000:af:00.0 'Ethernet Controller XXV710 for 25GbE SFP28 158b' if=enp175s0f0 drv=i40e unused=vfio-pci
+
+Generate 1 VF on PF::
+
+ echo 1 > /sys/bus/pci/devices/0000:af:00.0/sriov_numvfs
+
+Bind VFs to dpdk driver::
+
+ modprobe vfio-pci
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:af:01.0
+
+To run the testpmd application in linuxapp environment with 4 lcores,
+4 channels with other default parameters in interactive mode::
+
+ $ ./<build_target>/app/dpdk-testpmd -c 0xf -n 4 -- -i
+
+Test Case: vf queue start/stop
+------------------------------
+
+This case support VF (Intel® Ethernet 700 Series/Intel® Ethernet 800 Series)
+
+#. Launch testpmd::
+ x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 -a 0000:af:01.0 -- -i --portmask=0x1 --port-topology=loop
+
+#. Run "set verbose 1" to set verbose
+#. Run "set fwd mac" to set fwd type
+#. Run "start" to start fwd package
+
+#. Start a packet capture on the tester in the background::
+ tcpdump -i ens7 'ether[12:2] != 0x88cc' -Q in -w /tmp/tester/sniff_ens7.pcap
+
+#. Start packet generator to transmit packets::
+ sendp([Ether(dst='3c:fd:fe:c1:0f:4c', src='00:00:20:00:00:00')/IP()/UDP()/Raw(load=b'XXXXXXXXXXXXXXXXXX')],iface="ens7",count=4,inter=0,verbose=False)
+
+#. Quit tcpdump and check tester port receive packets

+#. Run "port 0 rxq 0 stop" to stop rxq 0 in port 0
