-Description
-===========
-
-For PFCP protocal, the destination port value of the outer UDP header is equal to 8805(0x2265)
-PFCP Node headers shall be identified when the Version field is equal to 001 and the S field is equal 0.
-PFCP Session headers shall be identified when the Version field is equal to 001 and the S field is equal 1.
 
-CVL supports PFCP protocols in advanced iavf, the supported pattern as below::

-Prerequisites
-=============
-
-Create a VF interface from kernel PF interfaces, and then attach them to VM. Suppose PF is 0000:18:00.0 . 
-Generate a VF using commands below and make them in pci-stub mods.
-
-NIC: 4x25G or 2x100G, several TC need breakout mode, then 2x100G is required
-PF: The 1st PF's PCI address 0000:18:00.0 , kernel interface name enp24s0f0 . The 2nd PF's PCI address 0000:18:00.1 , kernel interface name enp24s0f1
-VF: The VFs generated by 0000:18:00.0 , are 0000:18:02.x , The VFs generated by 0000:18:00.1 , are 0000:18:0a.x
-
-Copy correct ``ice.pkg`` into ``/usr/lib/firmware/intel/ice/ddp/``, 
-For the test cases, comms package is expected.
-
-Prepare test toplogoy, in the test case, it requires
-
-- 1 Intel E810 interface
-- 1 network interface enp134s0f0 for sending test packet, which could be connect to the E810 interface
-- Directly connect the 2 interfaces
-- Latest driver and comms pkgs of version
-
-Compile DPDK and testpmd::
-
-    make install -j T=x86_64-native-linuxapp-gcc
-
-1. Create 1 VF from a PF, and set VF mac address::
-
-    echo 1 > /sys/bus/pci/devices/0000\:18\:00.0/sriov_numvfs
-    ip link set enp24s0f0 vf 0 mac 00:11:22:33:44:55
-          
-2. Bind VF to vfio-pci::
-
-    ./usertools/dpdk-devbind.py -b vfio-pci 0000:18:02.0 
-
-3. Bring up PF and tester port::
-
-    ifconfig enp24s0f0 up
-    ifconfig enp134s0f0 up
-
-4. Launch the testpmd::
-
-    ./x86_64-native-linux-gcc/app/testpmd -l 6-9 -n 4 -w 18:02.0 -- -i --rxq=16 --txq=16 --portmask=0x1 --nb-cores=2
-    testpmd>set verbose 1
-    testpmd>set fwd rxonly
-    testpmd>start
-
-5. on tester side, add pfcp.py to "scapy/layers", and copy it to "/root".
-   add "pfcp" to "load_layers" in "scapy/config.py", then start scapy::
- 
-    >>> import sys
-    >>> sys.path.append('/root)
-    >>> from pfcp import PFCP
-    >>>from scapy.contrib.pfcp import *
