+=========================
+CVL support QinQ protocol
+=========================
+DPDK support QinQ protocol in CVL as below requirements:
+* DCF support QinQ by add steering rule and vlan strip disable.
+* DCF is able to set port vlan by port representor.
+* AVF is able to configure inner VLAN filter when port vlan is enabled base on negotiation.
+* AVF is able to configure outer VLAN (8100) if no port VLANis enabled to compatible with legacy mode.
+this test plan contain 3 parts to cover above requirements:
+* DCF switch filter for QinQ.
+* DCF pvid support for QinQ.
+* AVF VLAN offload for QinQ.

+Prerequisites
+=============
+1. Hardware:
+   columbiaville_25g/columbiaville_100g
+
+2. Software:
+   dpdk: http://dpdk.org/git/dpdk
+   scapy: http://www.secdev.org/projects/scapy/
+
+3. Copy specific ice package to /lib/firmware/updates/intel/ice/ddp/ice.pkg,
+   then load driver::
+
+    rmmod ice
+    insmod ice.ko
+
+4. Compile DPDK::
+
+    CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib --default-library=static x86_64-native-linuxapp-gcc
+    ninja -C x86_64-native-linuxapp-gcc -j 110
+
+5. Get the pci device id of DUT, for example::
+
+    ./usertools/dpdk-devbind.py -s
+
+    0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+    0000:18:00.1 'Device 159b' if=ens785f1 drv=ice unused=vfio-pci
+
+6. Enable vlan prune flag::
+
+    ethtool --set-priv-flags ens785f0 vf-vlan-prune-disable on
+
+7. Generate 4 VFs on PF0(not all the VFs are used)::
+
+    echo 4 > /sys/bus/pci/devices/0000:18:00.0/sriov_numvfs
+
+    ./usertools/dpdk-devbind.py -s
+    0000:18:01.0 'Ethernet Adaptive Virtual Function 1889' if=ens785f0v0 drv=iavf unused=vfio-pci
+    0000:18:01.1 'Ethernet Adaptive Virtual Function 1889' if=ens785f0v1 drv=iavf unused=vfio-pci
+    0000:18:01.2 'Ethernet Adaptive Virtual Function 1889' if=ens785f0v2 drv=iavf unused=vfio-pci
+    0000:18:01.3 'Ethernet Adaptive Virtual Function 1889' if=ens785f0v3 drv=iavf unused=vfio-pci
+
+8. Set VF0 as trust::
+
+    ip link set ens785f0 vf 0 trust on
+
+9. Set mac addr for VF1, VF2 and VF3::
+
+    ip link set ens785f0 vf 1 mac 00:11:22:33:44:11
+    ip link set ens785f0 vf 2 mac 00:11:22:33:44:22
+    ip link set ens785f0 vf 3 mac 00:11:22:33:44:33
+
+10. Bind VFs to dpdk driver::
+
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py -b vfio-pci 0000:18:01.0 0000:18:01.1 0000:18:01.2 0000:18:01.3
+
+11. Disabel spoofchk for VF::
+
+    ip link set dev ens785f0 vf 0 spoofchk off
+    ip link set dev ens785f0 vf 1 spoofchk off
+    ip link set dev ens785f0 vf 2 spoofchk off
+    ip link set dev ens785f0 vf 3 spoofchk off
+
+12. For test cases for DCF switch filter(01-06), use below cmd to launch testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:18:01.0,cap=dcf -a 0000:18:01.1 -a 0000:18:01.2 -a 0000:18:01.3 -- -i
+    testpmd> set fwd rxonly
+    testpmd> set verbose 1
+    testpmd> start
+    testpmd> show port info all
+
+   check the VF0 driver is net_ice_dcf.
+
+   For test cases for DCF pvid(07-09), use below cmd to launch testpmd::
+
+   ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:18:01.0,cap=dcf,representor=[1] -a 0000:18:01.1 -a 0000:18:01.2 -a 0000:18:01.3 -- -i
+    testpmd> set fwd mac
+    testpmd> set verbose 1
+    testpmd> start
+    testpmd> show port info all
+
+   check the VF0 driver is net_ice_dcf.
+
+13. For AVF QinQ test cases(10-14), recreate Generate 1 VFs on PF0, reconfig the VF then launch testpmd::
+
+    echo 0 > /sys/bus/pci/devices/0000:18:00.0/sriov_numvfs
+    ethtool --set-priv-flags ens785f0 vf-vlan-prune-disable off
+    echo 1 > /sys/bus/pci/devices/0000:18:00.0/sriov_numvfs
+    ip link set ens785f0 vf 0 mac 00:11:22:33:44:11
+    ip link set dev ens785f0 vf 0 spoofchk off
+
+    ./usertools/dpdk-devbind.py -b vfio-pci 0000:18:01.0
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0xf -n 4 -a 0000:18:01.0 -- -i --rxq=16 --txq=16

+Test case 08: vlan insertion when pvid enable
+=============================================
+
+1. add tx port vlan for VF1 by representor 1::
+
+    testpmd> tx_vlan set pvid 1 24 on
+
+    Port 2: reset event
+
+2. reset VF1::
+
+    testpmd> port stop 2
+    testpmd> port reset 2
+    testpmd> port start 2
+    testpmd> start
+
+3. send a pkt without vlan header to VF2(VF2 rx, VF1 tx)::
+
+    sendp([Ether(dst="00:11:22:33:44:22",type=0x0800)/IP(src="196.222.232.221")/("X"*480)], iface="ens786f0")

+
+4. check the dpdk can receive this pkt with VF2 and fwd this pkt with outer vlan header id 24 by VF1, and the vlan header ptype is 8100::
