Because VF multi-queues can be supported, l3fwd can run on vf.
Suggest to remove the l3fwd-vf example.

-L3 Forwarding in a Virtualization Environment Sample Application
-================================================================
-
-The L3 Forwarding in a Virtualization Environment sample application is a
simple example of packet processing using the DPDK.
-The application performs L3 forwarding that takes advantage of Single Root I/O
Virtualization (SR-IOV) features
-in a virtualized environment.
-
-Overview
---------
-
-The application demonstrates the use of the hash and LPM libraries in the DPDK
to implement packet forwarding.
-The initialization and run-time paths are very similar to those of the L3
forwarding application
-(see Chapter 10 "L3 Forwarding Sample Application" for more information).
-The forwarding decision is taken based on information read from the input
packet.
-
-The lookup method is either hash-based or LPM-based and is selected at compile
time.
-When the selected lookup method is hash-based, a hash object is used to
emulate the flow classification stage.
-The hash object is used in correlation with the flow table to map each input
packet to its flow at runtime.
-
-The hash lookup key is represented by the DiffServ 5-tuple composed of the
following fields read from the input packet:
-Source IP Address, Destination IP Address, Protocol, Source Port and
Destination Port.
-The ID of the output interface for the input packet is read from the
identified flow table entry.
-The set of flows used by the application is statically configured and loaded
into the hash at initialization time.
-When the selected lookup method is LPM based, an LPM object is used to emulate
the forwarding stage for IPv4 packets.
-The LPM object is used as the routing table to identify the next hop for each
input packet at runtime.
-
-The LPM lookup key is represented by the Destination IP Address field read
from the input packet.
-The ID of the output interface for the input packet is the next hop returned
by the LPM lookup.
-The set of LPM rules used by the application is statically configured and
loaded into the LPM object at the initialization time.
-
-.. note::
-
- Please refer to Section 9.1.1 "Virtual Function Setup Instructions" for
virtualized test case setup.
-
-Compiling the Application
--------------------------
-
-To compile the application:
-
-#. Go to the sample application directory:
-
- .. code-block:: console
-
- export RTE_SDK=/path/to/rte_sdk
- cd ${RTE_SDK}/examples/l3fwd-vf
-
-#. 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 possible RTE_TARGET values.
-
-#. Build the application:
-
- .. code-block:: console
-
- make
-
-.. note::
-
- The compiled application is written to the build subdirectory.
- To have the application written to a different location,
- the O=/path/to/build/directory option may be specified in the make command.
-
-Running the Application
------------------------
-
-The application has a number of command line options:
-
-.. code-block:: console
-
- ./build/l3fwd-vf [EAL options] -- -p PORTMASK
--config(port,queue,lcore)[,(port,queue,lcore)] [--no-numa]
-
-where,
-
-* --p PORTMASK: Hexadecimal bitmask of ports to configure
-
-* --config (port,queue,lcore)[,(port,queue,lcore]: determines which queues
from which ports are mapped to which cores
-
-* --no-numa: optional, disables numa awareness
-
-For example, consider a dual processor socket platform where cores 0,2,4,6, 8,
and 10 appear on socket 0,
-while cores 1,3,5,7,9, and 11 appear on socket 1.
-Let's say that the programmer wants to use memory from both NUMA nodes,
-the platform has only two ports and the programmer wants to use one core from
each processor socket to do the packet processing
-since only one Rx/Tx queue pair can be used in virtualization mode.
-
-To enable L3 forwarding between two ports, using one core from each processor,
-while also taking advantage of local memory accesses by optimizing around NUMA,
-the programmer can pin to the appropriate cores and allocate memory from the
appropriate NUMA node.
-This is achieved using the following command:
-
-.. code-block:: console
-
- ./build/l3fwd-vf -c 0x03 -n 3 -- -p 0x3 --config="(0,0,0),(1,0,1)"
-
-In this command:
-
-* The -c option enables cores 0 and 1
-
-* The -p option enables ports 0 and 1
-
-* The --config option enables one queue on each port and maps each
(port,queue) pair to a specific core.
- Logic to enable multiple RX queues using RSS and to allocate memory from
the correct NUMA nodes
- is included in the application and is done transparently.
- The following table shows the mapping in this example:
-
- +----------+-----------+-----------+------------------------------------+
- | **Port** | **Queue** | **lcore** | **Description** |
- | | | | |
- +==========+===========+===========+====================================+
- | 0 | 0 | 0 | Map queue 0 from port 0 to lcore 0 |
- | | | | |
- +----------+-----------+-----------+------------------------------------+
- | 1 | 1 | 1 | Map queue 0 from port 1 to lcore 1 |
- | | | | |
- +----------+-----------+-----------+------------------------------------+
-
-Refer to the *DPDK Getting Started Guide* for general information on running
applications
-and the Environment Abstraction Layer (EAL) options.
-
-Explanation
------------
-
-The operation of this application is similar to that of the basic L3
Forwarding Sample Application.
-See Section 10.4 "Explanation" for more information.
