TEP termination Sample Application
==================================
* TSO offload support for tunneling packet.
-The following figure shows the framework of the TEP termination sample application based on vhost-cuse.
+The following figure shows the framework of the TEP termination sample
+application based on DPDK vhost lib.
.. _figure_tep_termination_arch:
* Fedora* 20
-Prerequisites
--------------
-
-Refer to :ref:`vhost_app_prerequisites`.
-
Compiling the Sample Code
-------------------------
-#. Compile vhost lib:
- To enable vhost, turn on vhost library in the configure file config/common_linuxapp.
+To enable vhost, turn on vhost library in the configure file
+``config/common_linuxapp``.
.. code-block:: console
CONFIG_RTE_LIBRTE_VHOST=y
- 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=n
-
- 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
+Then following the to compile the sample application shown in
+:doc:`compiling`.
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
-
