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.
