+TEP termination Sample Application
+========================
+
+The TEP (Tunnel End point) termination sample application simulates a VXLAN Tunnel Endpoint (VTEP) termination in DPDK, which is used to
+demonstrate the offload and filtering capabilities of Intel® XL710 10/40 Gigabit Ethernet Controller for VXLAN packet.
+This sample uses the basic virtio devices management mechanism from vhost example, and also uses the us-vHost interface and
+tunnel filtering mechanism to direct a specified traffic to a specific VM.
+In addition, this sample is also designed to show how tunneling protocols can be handled.
+
+Background
+----------
+With virtualization, overlay networks allow a network structure to be built or imposed across physical nodes which
+is abstracted away from the actual underlining physical network connections. This allows network isolation, QOS, etc
+to be provided on a per client basis.
+
+.. _figure_overlay_networking:
+
+.. figure:: img/overlay_networking.*
+
+ Overlay Networking.
+
+In a typical setup, the network overlay tunnel is terminated at the Virtual/Tunnel End Point (VEP/TEP).
+The TEP is normally located at the physical host level ideally in the software switch. Due to processing constraints and
+the inevitable bottleneck that the switch becomes the ability to offload overlay support features becomes an important requirement.
+Intel® XL710 10/40 G Ethernet network card provides hardware filtering and offload capabilities to support overlay networks
+implementations such as MAC in UDP and MAC in GRE.
+
+Sample Code Overview
+--------------------
+
+The DPDK TEP termination sample code demonstrates the offload and filtering capabilities of Intel® XL710 10/40 Gigabit Ethernet
+Controller for VXLAN packet.
+
+The sample code is based on vhost library. The vhost library is developed for user space Ethernet switch to
+easily integrate with vhost functionality.
+
+The sample will support the followings:
+
+* Tunneling packet recognition.
+
+* The port of UDP tunneling is configurable
+
+* Directing incoming traffic to the correct queue based on the tunnel filter type.
+ The supported filter type are listed below.
+
+ * Inner MAC and VLAN and tenant ID
+
+ * Inner MAC and tenant ID, and Outer MAC
+
+ * Inner MAC and tenant ID
+
+ The tenant ID will be assigned from a static internal table based on the us-vhost device ID.
+ Each device will receive a unique device ID. The inner MAC will be learned by the first packet transmitted from a device.
+
+* Decapsulation of RX VXLAN traffic. This is a software only operation.
+
+* Encapsulation of TX VXLAN traffic. This is a software only operation.
+
+* Inner IP and inner L4 checksum offload.
+
+* TSO offload support for tunneling packet.
+
+The following figure shows the framework of the TEP termination sample application based on vhost-cuse.
+

+Refer to the guide in section 27.4 in the vhost sample.
+
+Compiling the Sample Code
+-------------------------
+#. Compile vhost lib:
+
+ To enable vhost, turn on vhost library in the configure file config/common_linuxapp.
+
+ .. code-block:: console
+
+ CONFIG_RTE_LIBRTE_VHOST=n
+
+ vhost user is turned on by default in the configure file config/common_linuxapp.
+ To enable vhost cuse, disable vhost user.
+
+ .. code-block:: console
+
+ CONFIG_RTE_LIBRTE_VHOST_USER=y
+
+ After vhost is enabled and the implementation is selected, build the vhost library.
+
+#. Go to the examples directory:
+
+ .. code-block:: console
+
+ export RTE_SDK=/path/to/rte_sdk
+ cd ${RTE_SDK}/examples/tep_termination
+
+#. Set the target (a default target is used if not specified). For example:
+
+ .. code-block:: console
+
+ export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+ See the DPDK Getting Started Guide for possible RTE_TARGET values.
+
+#. Build the application:
+
+ .. code-block:: console
+
+ cd ${RTE_SDK}
+ make config ${RTE_TARGET}
+ make install ${RTE_TARGET}
+ cd ${RTE_SDK}/examples/tep_termination
+ make
+
+#. Go to the eventfd_link directory(vhost cuse required):
+
+ .. code-block:: console
+
+ cd ${RTE_SDK}/lib/librte_vhost/eventfd_link
+
+#. Build the eventfd_link kernel module(vhost cuse required):
+
+ .. code-block:: console
+
+ make
+
+Running the Sample Code
+-----------------------
+
+#. Install the cuse kernel module(vhost cuse required):
+
+ .. code-block:: console
+
+ modprobe cuse
+
+#. Go to the eventfd_link directory(vhost cuse required):
+
+ .. code-block:: console
+
+ export RTE_SDK=/path/to/rte_sdk
+ cd ${RTE_SDK}/lib/librte_vhost/eventfd_link
+
+#. Install the eventfd_link module(vhost cuse required):
+
+ .. code-block:: console
+
+ insmod ./eventfd_link.ko
+
+#. Go to the examples directory:
+
+ .. code-block:: console
+
+ export RTE_SDK=/path/to/rte_sdk
+ cd ${RTE_SDK}/examples/tep_termination
+
+#. Run the tep_termination sample code:
+
+ .. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ -p 0x1 --dev-basename tep-termination --nb-devices 4
+ --udp-port 4789 --filter-type 1
+
+.. note::
+
+ Please note the huge-dir parameter instructs the DPDK to allocate its memory from the 2 MB page hugetlbfs.
+
+Parameters
+~~~~~~~~~~
+
+**The same parameters with the vhost sample.**
+
+Refer to the guide in section 27.6.1 in the vhost sample for the meanings of 'Basename',
+'Stats', 'RX Retry', 'RX Retry Number' and 'RX Retry Delay Time'.
+
+**Number of Devices.**
+
+The nb-devices option specifies the number of virtIO device.
+The default value is 2.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --nb-devices 2
+
+**Tunneling UDP port.**
+
+The udp-port option is used to specify the destination UDP number for UDP tunneling packet.
+The default value is 4789.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --nb-devices 2 --udp-port 4789
+
+**Filter Type.**
+
+The filter-type option is used to specify which filter type is used to filter UDP tunneling packet to a specified queue.
+The default value is 1, which means the filter type of inner MAC and tenant ID is used.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --nb-devices 2 --udp-port 4789 --filter-type 1
+
+**TX Checksum.**
+
+The tx-checksum option is used to enable or disable the inner header checksum offload.
+The default value is 0, which means the checksum offload is disabled.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --nb-devices 2 --tx-checksum
+
+**TCP segment sise.**
+
+The tso-segsz option specifies the TCP segment size for TSO offload for tunneling packet.
+The default value is 0, which means TSO offload is disabled.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --tx-checksum --tso-segsz 800
+
+**Decapsulation option.**
+
+The decap option is used to enable or disable decapsulation operation for received VXLAN packet.
+The default value is 1.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --nb-devices 4 --udp-port 4789 --decap 1
+
+**Encapsulation option.**
+
+The encap option is used to enable or disable encapsulation operation for transmitted packet.
+The default value is 1.
+
+.. code-block:: console
+
+ user@target:~$ ./build/app/tep_termination -c f -n 4 --huge-dir /mnt/huge --
+ --nb-devices 4 --udp-port 4789 --encap 1
+
+
+Running the Virtual Machine (QEMU)
+----------------------------------
+
+Refer to the guide in section 27.7 in the vhost sample.
+
+Running DPDK in the Virtual Machine
+-----------------------------------
+
+Refer to the guide in section 27.8 in the vHost sample.
+
+Passing Traffic to the Virtual Machine Device
+---------------------------------------------
+
+For a virtio-net device to receive traffic, the traffic's Layer 2 header must include
+both the virtio-net device's MAC address.
+The DPDK sample code behaves in a similar manner to a learning switch in that
+it learns the MAC address of the virtio-net devices from the first transmitted packet.
+On learning the MAC address,
+the DPDK vhost sample code prints a message with the MAC address and tenant ID virtio-net device.
+For example:
+
+.. code-block:: console
+
+ DATA: (0) MAC_ADDRESS cc:bb:bb:bb:bb:bb and VNI 1000 registered
+
+The above message indicates that device 0 has been registered with MAC address cc:bb:bb:bb:bb:bb and VNI 1000.
+Any packets received on the NIC with these values are placed on the devices receive queue.

> +TEP termination Sample Application
> +========================
> +
> +The TEP (Tunnel End point) termination sample application simulates a
> VXLAN Tunnel Endpoint (VTEP) termination in DPDK, which is used to
> +demonstrate the offload and filtering capabilities of Intel® XL710 10/40
> Gigabit Ethernet Controller for VXLAN packet.
> +This sample uses the basic virtio devices management mechanism from vhost
> example, and also uses the us-vHost interface and
> +tunnel filtering mechanism to direct a specified traffic to a specific VM.
> +In addition, this sample is also designed to show how tunneling protocols
> can be handled.
> +
> +Background
> +----------
> +With virtualization, overlay networks allow a network structure to be
> built or imposed across physical nodes which
> +is abstracted away from the actual underlining physical network
> connections. This allows network isolation, QOS, etc
> +to be provided on a per client basis.

> + Overlay Networking.
> +
> +In a typical setup, the network overlay tunnel is terminated at the
> Virtual/Tunnel End Point (VEP/TEP).
> +The TEP is normally located at the physical host level ideally in the
> software switch. Due to processing constraints and
> +the inevitable bottleneck that the switch becomes the ability to offload
> overlay support features becomes an important requirement.
> +Intel® XL710 10/40 G Ethernet network card provides hardware filtering

> +Controller for VXLAN packet.
> +
> +The sample code is based on vhost library. The vhost library is developed

> +* Tunneling packet recognition.
> +
> +* The port of UDP tunneling is configurable
> +
> +* Directing incoming traffic to the correct queue based on the tunnel
> filter type.
> + The supported filter type are listed below.
> +
> + * Inner MAC and VLAN and tenant ID
> +
> + * Inner MAC and tenant ID, and Outer MAC
> +
> + * Inner MAC and tenant ID
> +
> + The tenant ID will be assigned from a static internal table based on

> + Each device will receive a unique device ID. The inner MAC will be

To avoid big margins around pictures, SVG files have been resized to content.
The RST file have been wrapped.
Applied, thanks
