+================================
+test coverage for L2TPv3 and ESP 
+================================
+
+Description
+===========
+For each protocol, below is a list of standard features supported by the Columbiaville hardware and the impact on the feature for each protocol.  
+Some features are supported in a limited manner as stated below.
+ 
+IPSec(ESP):
+L2 Tag offloads 
+----L2 Tag Stripping - Yes
+----L2 Tag insertion - Yes
+Checksum offloads - Yes 
+----Only outer layer 3 checksum for IP+ESP and IP+AH packets
+----Outer layer 3 and 4 checksum for ESP over UDP packets
+Manageability - No 
+----Packets must be excluded
+RDMA - No 
+----Packets must be excluded
+DCB 
+----Priority Flow Control - No
+ 
+L2TPv3:
+L2 Tag offloads 
+----L2 Tag Stripping - Yes
+----L2 Tag insertion - Yes
+Checksum offloads - Yes 
+----Only outer layer 3
+Manageability - No 
+----Packets must be excluded
+RDMA - No 
+----Packets must be excluded
+DCB 
+----Priority Flow Control - No
+
+this test plan is designed to check above offloads in L2TPv3 and ESP.
+and CVL can't support tx checksum in vector path now, so only test the rx checksum offload.
+
+
+Prerequisites
+=============
+
+1. create a vf from a pf::
+
+    echo 1 > /sys/bus/pci/devices/0000\:af\:00.0/sriov_numvfs
+    ip link set enp175s0f0 vf 0 mac 00:11:22:33:44:55
+
+2. bind vf to vfio-pci::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci af:01.0
+
+
+Test Case 1: test MAC_IPV4_L2TPv3 HW checksum offload
+=====================================================
+
+1. DUT enable rx checksum with "--enable-rx-cksum" when start testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -n 4 -w af:01.0 -- -i --enable-rx-cksum
+
+2. DUT setup csum forwarding mode::
+
+    testpmd> port stop all
+    testpmd> csum set ip hw 0
+    testpmd> port start all
+    testpmd> set fwd csum
+    testpmd> set verbose 1
+    testpmd> start
+
+3. Tester send MAC_IPV4_L2TPv3 packets with correct checksum::
+
+    sendp([Ether(dst="00:11:22:33:44:55")/IP(src="192.168.0.3", proto=115)/L2TP('\x00\x00\x00\x11')/Raw('x'*480)], iface="enp134s0f0")
+    
+4. DUT check the packets are correctly received with "PKT_RX_IP_CKSUM_GOOD" by DUT::
+
+    testpmd> port 0/queue 0: received 1 packets
+    src=00:00:00:00:00:00 - dst=00:11:22:33:44:55 - type=0x0800 - length=518 - nb_segs=1 - RSS hash=0x0 - RSS queue=0x0 - sw ptype: L2_ETHER L3_IPV4  - l2_len=14 - l3_len=20 - Receive queue=0x0

+Test Case 17: MAC_IPV6_NAT-T-ESP vlan insert on + SW checksum offload check
+===========================================================================
+
+1. ./x86_64-native-linuxapp-gcc/app/testpmd -l 6-9 -n 4 -w af:01.0 -- -i --rxq=16 --txq=16 --portmask=0x1 --nb-cores=2 --enable-rx-cksum
+
+2. DUT create fdir rules for MAC_IPV6_NAT-T-ESP with queue index and mark::
+
+    flow create 0 ingress pattern eth / ipv4 / udp / esp spi is 1 / end actions queue index 1 / mark id 4 / end
+    flow create 0 ingress pattern eth / ipv4 / udp / esp spi is 2 / end actions queue index 2 / mark id 3 / end
+    flow create 0 ingress pattern eth / ipv4 / udp / esp spi is 3 / end actions queue index 3 / mark id 2 / end
+    flow create 0 ingress pattern eth / ipv4 / udp / esp spi is 4 / end actions queue index 4 / mark id 1 / end
+
+3. Enable vlan filter and add tx vlan offload on port 0::
+
+    testpmd> port stop all
+    testpmd> rx_vlan add 1 0
+    testpmd> vlan set filter on 0
+    testpmd> tx_vlan set 0 1
+    testpmd> port start all

+
+4. Tester send matched packets without vlan::

+    
+5. DUT check the packets are distributed to expected queue with mark id and fwd with VLAN tag "1" to tester::

+6. enable sw checksum::
