Application\n-================================================================\n-\n-The L3 Forwarding in a Virtualization Environment sample application is a simple example of packet processing using the DPDK.\n-The application performs L3 forwarding that takes advantage of Single Root I/O Virtualization (SR-IOV) features\n-in a virtualized environment.\n-\n-Overview\n---------\n-\n-The application demonstrates the use of the hash and LPM libraries in the DPDK to implement packet forwarding.\n-The initialization and run-time paths are very similar to those of the :doc:`l3_forward`.\n-The forwarding decision is taken based on information read from the input packet.\n-\n-The lookup method is either hash-based or LPM-based and is selected at compile time.\n-When the selected lookup method is hash-based, a hash object is used to emulate the flow classification stage.\n-The hash object is used in correlation with the flow table to map each input packet to its flow at runtime.\n-\n-The hash lookup key is represented by the DiffServ 5-tuple composed of the following fields read from the input packet:\n-Source IP Address, Destination IP Address, Protocol, Source Port and Destination Port.\n-The ID of the output interface for the input packet is read from the identified flow table entry.\n-The set of flows used by the application is statically configured and loaded into the hash at initialization time.\n-When the selected lookup method is LPM based, an LPM object is used to emulate the forwarding stage for IPv4 packets.\n-The LPM object is used as the routing table to identify the next hop for each input packet at runtime.\n-\n-The LPM lookup key is represented by the Destination IP Address field read from the input packet.\n-The ID of the output interface for the input packet is the next hop returned by the LPM lookup.\n-The set of LPM rules used by the application is statically configured and loaded into the LPM object at the initialization time.\n-\n-.. note::\n-\n-    Please refer to :ref:`l2_fwd_vf_setup` for virtualized test case setup.\n-\n-Compiling the Application\n--------------------------\n-\n-To compile the sample application see :doc:`compiling`.\n-\n-The application is located in the ``l3fwd-vf`` sub-directory.\n-\n-Running the Application\n------------------------\n-\n-The application has a number of command line options:\n-\n-.. code-block:: console\n-\n-    ./build/l3fwd-vf [EAL options] -- -p PORTMASK  --config(port,queue,lcore)[,(port,queue,lcore)] [--no-numa]\n-\n-where,\n-\n-*   --p PORTMASK: Hexadecimal bitmask of ports to configure\n-\n-*   --config (port,queue,lcore)[,(port,queue,lcore]: determines which queues from which ports are mapped to which cores\n-\n-*   --no-numa: optional, disables numa awareness\n-\n-For example, consider a dual processor socket platform with 8 physical cores, where cores 0-7 and 16-23 appear on socket 0,\n-while cores 8-15 and 24-31 appear on socket 1.\n-\n-To enable L3 forwarding between two ports, assuming that both ports are in the same socket, using two cores, cores 1 and 2,\n-(which are in the same socket too), use the following command:\n-\n-.. code-block:: console\n-\n-   ./build/l3fwd-vf -l 1,2 -n 4 -- -p 0x3 --config=\"(0,0,1),(1,0,2)\"\n-\n-In this command:\n-\n-*   The -l option enables cores 1 and 2\n-\n-*   The -p option enables ports 0 and 1\n-\n-*   The --config option enables one queue on each port and maps each (port,queue) pair to a specific core.\n-    The following table shows the mapping in this example:\n-\n-    +----------+-----------+-----------+------------------------------------+\n-    | **Port** | **Queue** | **lcore** | **Description**                    |\n-    |          |           |           |                                    |\n-    +==========+===========+===========+====================================+\n-    | 0        | 0         | 1         | Map queue 0 from port 0 to lcore 1 |\n-    |          |           |           |                                    |\n-    +----------+-----------+-----------+------------------------------------+\n-    | 1        | 0         | 2         | Map queue 0 from port 1 to lcore 2 |\n-    |          |           |           |                                    |\n-    +----------+-----------+-----------+------------------------------------+\n-\n-Refer to the *DPDK Getting Started Guide* for general information on running applications\n-and the Environment Abstraction Layer (EAL) options.\n-\n-Explanation\n------------\n-\n-The operation of this application is similar to that of the basic L3 Forwarding Sample Application.\n-See :ref:`l3_fwd_explanation` for more information.\ndiff --git a/examples/Makefile b/examples/Makefile\nindex c756497d1..5dd8a72e5 100644\n--- a/examples/Makefile\n+++ b/examples/Makefile\n@@ -46,7 +46,6 @@ endif\n
