+Netmap Compatibility Sample Application
+=======================================
+
+Introduction
+------------
+
+The Netmap compatibility library provides a minimal set of APIs to give programs written against the Netmap APIs
+the ability to be run, with minimal changes to their source code, using the DPDK to perform the actual packet I/O.
+
+Since Netmap applications use regular system calls, like ``open()``, ``ioctl()`` and
+``mmap()`` to communicate with the Netmap kernel module performing the packet I/O,
+the ``compat_netmap`` library provides a set of similar APIs to use in place of those system calls,
+effectively turning a Netmap application into a DPDK application.
+
+The provided library is currently minimal and doesn't support all the features that Netmap supports,
+but is enough to run simple applications, such as the bridge example detailed below.
+
+Knowledge of Netmap is required to understand the rest of this section.
+Please refer to the Netmap distribution for details about Netmap.
+
+
+Compiling the "bridge" Sample Application
+-----------------------------------------
+
+#.  Go to the example directory:
+
+    .. code-block:: console
+
+        export RTE_SDK=/path/to/rte_sdk
+        cd ${RTE_SDK}/examples/netmap_compat
+
+#.  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 Linux* for possible ``RTE_TARGET`` values.
+
+#.  Build the application:
+
+    .. code-block:: console
+
+        make
+
+Running the "bridge" Sample Application
+---------------------------------------
+
+The application requires a single command line option:
+
+.. code-block:: console
+
+    ./build/bridge [EAL options] -- -i INTERFACE_A [-i INTERFACE_B]
+
+where,
+
+*   ``-i INTERFACE``: Interface (DPDK port number) to use.
+
+    If a single ``-i`` parameter is given, the interface will send back all the traffic it receives.
+    If two ``-i`` parameters are given, the two interfaces form a bridge,
+    where traffic received on one interface is replicated and sent to the other interface.
+
+For example, to run the application in a linuxapp environment using port 0 and 2:
+
+.. code-block:: console
+
+    ./build/bridge [EAL options] -- -i 0 -i 2
+
+Refer to the *DPDK Getting Started Guide for Linux* for general information on running applications and
+the Environment Abstraction Layer (EAL) options.
+
+Test Case1: netmap compat with one port 
+=======================================
+Run bridge with one port::
+        ./examples/netmap_compat/build/bridge -c 0x1e -n 4 -- -i 0
+waked up :
+        Port 0 now in Netmap mode
+        Bridge up and running!
+
+Send one packet on Port0,check this port receive packet. 
+It receive one packet that it send.
+
+Test Case2: netmap compat with two port
+=======================================
+Run bridge with one port::
+        ./examples/netmap_compat/build/bridge -c 0x1e -n 4 -- -i 0 -i 1
+waked up :
+        Port 0 now in Netmap mode
+        Port 1 now in Netmap mode
+        Bridge up and running!
+
+Send one packet on Port0,check the port1 receive packet.
+It receive one packet that the port0 send.
