+
+RX/TX Callbacks Sample Application
+==================================
+
+The RX/TX Callbacks sample application is a packet forwarding application that
+demonstrates the use of user defined callbacks on received and transmitted
+packets. The application performs a simple latency check, using callbacks, to
+determine the time packets spend within the application.
+
+In the sample application a user defined callback is applied to all received
+packets to add a timestamp. A separate callback is applied to all packets
+prior to transmission to calculate the elapsed time, in CPU cycles.
+
+
+Compiling the Application
+-------------------------
+
+To compile the application export the path to the DPDK source tree and go to
+the example directory:
+
+.. code-block:: console
+
+    export RTE_SDK=/path/to/rte_sdk
+
+    cd ${RTE_SDK}/examples/rxtx_callbacks
+
+
+Set the target, for example:
+
+.. code-block:: console
+
+    export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+See the *DPDK Getting Started* Guide for possible ``RTE_TARGET`` values.
+
+The callbacks feature requires that the ``CONFIG_RTE_ETHDEV_RXTX_CALLBACKS``
+setting is on in the ``config/common_`` config file that applies to the
+target. This is generally on by default:
+
+.. code-block:: console
+
+    CONFIG_RTE_ETHDEV_RXTX_CALLBACKS=y
+
+Build the application as follows:
+
+.. code-block:: console
+
+    make
+
+
+Running the Application
+-----------------------
+
+To run the example in a ``linuxapp`` environment:
+
+.. code-block:: console
+
+    ./build/rxtx_callbacks -c 2 -n 4
+
+Refer to *DPDK Getting Started Guide* for general information on running
+applications and the Environment Abstraction Layer (EAL) options.
+
+test_rxtx_callbacks

+
+Runing::
+     ./examples/rxtx_callbacks/build/rxtx_callbacks -c 2 -n 4
