+L2 Forwarding Sample Application (in Real and Virtualized Environments) with core load statistics.
+==================================================================================================
+
+The L2 Forwarding sample application is a simple example of packet processing using
+the Data Plane Development Kit (DPDK) which
+also takes advantage of Single Root I/O Virtualization (SR-IOV) features in a virtualized environment.
+
+.. note::
+
+    This application is a variation of L2 Forwarding sample application. It demonstrate possible
+    scheme of job stats library usage therefore some parts of this document is identical with original
+    L2 forwarding application.
+
+Overview
+--------
+
+The L2 Forwarding sample application, which can operate in real and virtualized environments,
+performs L2 forwarding for each packet that is received.
+The destination port is the adjacent port from the enabled portmask, that is,
+if the first four ports are enabled (portmask 0xf),
+ports 1 and 2 forward into each other, and ports 3 and 4 forward into each other.
+Also, the MAC addresses are affected as follows:
+
+*   The source MAC address is replaced by the TX port MAC address
+
+*   The destination MAC address is replaced by  02:00:00:00:00:TX_PORT_ID
+
+Running the Application
+-----------------------
+
+The application requires a number of command line options:
+
+.. code-block:: console
+
+    ./build/l2fwd-jobstats [EAL options] -- -p PORTMASK [-q NQ] [-l]
+
+where,
+
+*   p PORTMASK: A hexadecimal bitmask of the ports to configure
+
+*   q NQ: A number of queues (=ports) per lcore (default is 1)
+
+*   l: Use locale thousands separator when formatting big numbers.
+
+To run the application in linuxapp environment with 4 lcores, 16 ports, 8 RX queues per lcore and
+thousands  separator printing, issue the command:
+
+.. code-block:: console
+
+    $ ./build/l2fwd-jobstats -c f -n 4 -- -q 8 -p ffff -l
+
+Refer to the *DPDK Getting Started Guide* for general information on running applications
+and the Environment Abstraction Layer (EAL) options.
