+============
+Vxlan Sample
+============
+Vxlan sample simulates a VXLAN Tunnel Endpoint (VTEP) termination in DPDK.
+It is used to demonstrate the offload and filtering capabilities of i40 NIC
+for VXLAN packet.
+
+Vxlan sample uses the basic virtio devices management function from vHOST 
+example, and the US-vHost interface and tunnel filtering mechanism to direct 
+the traffic to/from a specific VM.
+
+Vxlan sample is also designed to show how tunneling protocols can be handled. 
+
+Prerequisites
+=============
+1x Intel® X710 (Fortville) NICs (2x 40GbE full duplex optical ports per NIC)
+plugged into the available PCIe Gen3 8-lane slot.
+
+2x Intel® XL710-DA4 (Eagle Fountain) (1x 10GbE full duplex optical ports per NIC)
+plugged into the avaiable PCIe Gen3 8-lane slot.
+
+DUT board must be two sockets system and each cpu have more than 8 lcores.
+
+Update qemu-system-x86_64 to version 2.2.0 which support hugepage based memory.
+Prepare vhost-use requested modules::
+
+    modprobe fuse
+    modprobe cuse
+    insmod lib/librte_vhost/eventfd_link/eventfd_link.ko
+
+Allocate 4096*2M hugepages for vm and dpdk::
+
+    echo 4096 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
+
+Test Case: Vxlan Sample Encap packet
+====================================
+Start vxlan sample with only encapsulation enable::
+
+    tep_termination -c 0xf -n 3 --socket-mem 2048,2048 -- -p 0x1 \
+        --udp-port 4789 --nb-devices 2 --filter-type 3 --tx-checksum 0 \
+        --encap 1 --decap 0
+
+Wait for vhost-net socket device created and message dumped::
+
+    VHOST_CONFIG: bind to vhost-net
+
+Start virtual machine with hugepage based memory and two vhost-user devices::
+
+    qemu-system-x86_64 -name vm0 -enable-kvm -daemonize \
+      -cpu host -smp 4 -m 4096 \
+      -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on \
+      -numa node,memdev=mem -mem-prealloc \

+      -netdev type=vhost-user,id=netdev1,chardev=char1,vhostforce \
+      -device virtio-net-pci,netdev=netdev1,mac=00:00:20:00:00:21 \
+      -drive file=/storage/vm-image/vm0.img -vnc :1
+Login into virtual machine and start testpmd with additional arguments::
+
+    testpmd -c f -n 3 -- -i --txqflags=0xf00 --disable-hw-vlan
+
+Start packet forward of testpmd and transit several packets for mac learning::
+
+    testpmd> set fwd mac
+    testpmd> start tx_first
+
+Make sure virtIO port registered normally::
+
+    VHOST_CONFIG: virtio is now ready for processing.
+    VHOST_DATA: (1) Device has been added to data core 56
+    VHOST_DATA: (1) MAC_ADDRESS 00:00:20:00:00:21 and VNI 1000 registered
+    VHOST_DATA: (0) MAC_ADDRESS 00:00:20:00:00:20 and VNI 1000 registered
+
+Send normal udp packet to PF device and packet dmac match PF device 
+Verify packet has been recevied in virtIO port0 and forwarded by port1::
+
+      testpmd> show port stats all
+
+Verify encapsulated packet received on PF device
+
+Test Case: Vxlan Sample Decap packet
+====================================
+Start vxlan sample with only de-capsulation enable::
+
+  tep_termination -c 0xf -n 3 --socket-mem 2048,2048 -- -p 0x1 \
+    --udp-port 4789 --nb-devices 2 --filter-type 3 --tx-checksum 0 \
+    --encap 0 --decap 1
+
+Start vhost-user test environment like case vxlan_sample_encap.
+
+Send vxlan packet Ether(dst=PF mac)/IP/UDP/vni(1000)/
+  Ether(dst=virtIO port0)/IP/UDP to PF device::
+
+Verify that packet received by virtIO port0 and forwarded by virtIO port1::
+
+  testpmd> show port stats all
+
+Verify that PF received packet just the same as inner packet
+
+Send vxlan packet Ether(dst=PF mac)/IP/UDP/vni(1000)/
+    Ether(dst=virtIO port1)/IP/UDP to PF device
+
+Verify that packet received by virtIO port1 and forwarded by virtIO port0::
+
+  testpmd> show port stats all  
+
+Make sure PF received packet received inner packet with mac reversed.
+
+Test Case: Vxlan Sample Encap and Decap
+=======================================
+Start vxlan sample with only de-capsulation enable::

+
+Verify that packet recevied by virtIO port0 and forwarded by virtIO port1::
+
+  testpmd> show port stats all
+
+Verify encapsulated packet received on PF device.

+
+  tep_termination -c 0xf -n 3 --socket-mem 2048,2048 -- -p 0x1 \
+    --udp-port 4789 --nb-devices 2 --filter-type 3 --tx-checksum 1 \
