+===================
+L2fwd Jobstats Test
+===================
+
+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 0x3), ports 0 and 1 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
+
+Prerequisites
+=============
+
+If using vfio the kernel must be >= 3.6+ and VT-d must be enabled in bios.When
+using vfio, use the following commands to load the vfio driver and bind it
+to the device under test::
+
+    modprobe vfio
+    modprobe vfio-pci
+    usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id
+
+The application requires a number of command line options::
+
+    ./build/l2fwd-jobstats [EAL options] -- -p PORTMASK [-q NQ] [-l]
+
+The ``l2fwd-jobstats`` application is run with EAL parameters and parameters for
+the application itself. For details about the EAL parameters, see the relevant
+DPDK **Getting Started Guide**. This application supports three parameters for
+itself.
+
+- 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.
+
+Test Case: L2fwd jobstats check
+================================================
+
+Assume port 0 and 1 are connected to the traffic generator, to run the test
+application in linuxapp environment with 4 lcores, 2 ports and 2 RX queues
+per lcore::
+
+    ./examples/l2fwd-jobstats/build/l2fwd-jobstats -c 0x03 -n 4  -- -q 2 -p 0x03 -l
+
+Then send 100, 000 packet to port 0 and 100, 000 packets to port 1, check the
+NIC packets number reported by sample is the same with what we set at the packet
+generator side.
