-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.
-
-Available APIs
---------------
-
-The library provides the following drop-in replacements for system calls usually used in Netmap applications:
-
-* ``rte_netmap_close()``
-
-* ``rte_netmap_ioctl()``
-
-* ``rte_netmap_open()``
-
-* ``rte_netmap_mmap()``
-
-* ``rte_netmap_poll()``
-
-They use the same signature as their libc counterparts, and can be used as drop-in replacements in most cases.
-
-Caveats
--------
-
-Given the difference between the way Netmap and the DPDK approach packet I/O,
-there are caveats and limitations to be aware of when trying to use the ``compat_netmap`` library, the most important of these are listed below.
-These may change as the library is updated:
-
-*   Any system call that can potentially affect file descriptors cannot be used with a descriptor returned by the ``rte_netmap_open()`` function.
-
-Note that:
-
-*   The ``rte_netmap_mmap()`` function merely returns the address of a DPDK memzone.
-    The address, length, flags, offset, and other arguments are ignored.
-
-*   The ``rte_netmap_poll()`` function only supports infinite (negative) or zero time outs.
-    It effectively turns calls to the ``poll()`` system call made in a Netmap application into polling of the DPDK ports,
-    changing the semantics of the usual POSIX defined poll.
-
-*   Not all of Netmap's features are supported: host rings,
-    slot flags and so on are not supported or are simply not relevant in the DPDK model.
-
-*   The Netmap manual page states that "*a device obtained through /dev/netmap also supports the ioctl supported by network devices*".
-    This is not the case with this compatibility layer.
-
-*   The Netmap kernel module exposes a sysfs interface to change some internal parameters, such as the size of the shared memory region.
-    This interface is not available when using this compatibility layer.
-
-Porting Netmap Applications
----------------------------
-
-Porting Netmap applications typically involves two major steps:
-
-*   Changing the system calls to use their ``compat_netmap`` library counterparts.
-
-*   Adding further DPDK initialization code.
-
-Since the ``compat_netmap`` functions have the same signature as the usual libc calls, the change is trivial in most cases.
-
-The usual DPDK initialization code involving ``rte_eal_init()`` and ``rte_pci_probe()``
-has to be added to the Netmap application in the same way it is used in all other DPDK sample applications.
-Please refer to the *DPDK Programmer's Guide* and example source code for details about initialization.
-
-In addition of the regular DPDK initialization code,
-the ported application needs to call initialization functions for the ``compat_netmap`` library,
-namely ``rte_netmap_init()`` and ``rte_netmap_init_port()``.
-
-These two initialization functions take ``compat_netmap`` specific data structures as parameters:
-``struct rte_netmap_conf`` and ``struct rte_netmap_port_conf``.
-The structures' fields are Netmap related and are self-explanatory for developers familiar with Netmap.
-They are defined in ``$RTE_SDK/examples/netmap_compat/lib/compat_netmap.h``.
-
-The bridge application is an example largely based on the bridge example shipped with the Netmap distribution.
-It shows how a minimal Netmap application with minimal and straightforward source code changes can be run on top of the DPDK.
-Please refer to ``$RTE_SDK/examples/netmap_compat/bridge/bridge.c`` for an example of a ported application.
-
-Compiling the Application
--------------------------
-
-To compile the sample application see :doc:`compiling`.
-
-The application is located in the ``netmap_compat`` sub-directory.
-
-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 linux 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.
-
-Note that unlike a traditional bridge or the ``l2fwd`` sample application, no MAC address changes are done on the frames.
-Do not forget to take this into account when configuring a traffic generators and testing this sample application.

- * Netmap representation of a TX or RX ring (also known as "queue").
- * This is a queue implemented as a fixed-size circular array.
- * At the software level, two fields are important: avail and cur.
- *
- * In TX rings:
- *	avail	indicates the number of slots available for transmission.
- *		It is updated by the kernel after every netmap system call.
- *		It MUST BE decremented by the application when it appends a
- *		packet.
- *	cur	indicates the slot to use for the next packet
- *		to send (i.e. the "tail" of the queue).
- *		It MUST BE incremented by the application before
- *		netmap system calls to reflect the number of newly
- *		sent packets.
- *		It is checked by the kernel on netmap system calls
- *		(normally unmodified by the kernel unless invalid).
- *
- *   The kernel side of netmap uses two additional fields in its own
- *   private ring structure, netmap_kring:
- *	nr_hwcur is a copy of nr_cur on an NIOCTXSYNC.
- *	nr_hwavail is the number of slots known as available by the
- *		hardware. It is updated on an INTR (inc by the
- *		number of packets sent) and on a NIOCTXSYNC
- *		(decrease by nr_cur - nr_hwcur)
- *		A special case, nr_hwavail is -1 if the transmit
- *		side is idle (no pending transmits).
- *
- * In RX rings:
- *	avail	is the number of packets available (possibly 0).
- *		It MUST BE decremented by the application when it consumes
- *		a packet, and it is updated to nr_hwavail on a NIOCRXSYNC
- *	cur	indicates the first slot that contains a packet not
- *		processed yet (the "head" of the queue).
- *		It MUST BE incremented by the software when it consumes
- *		a packet.
- *	reserved	indicates the number of buffers before 'cur'
- *		that the application has still in use. Normally 0,
- *		it MUST BE incremented by the application when it
- *		does not return the buffer immediately, and decremented
- *		when the buffer is finally freed.
- *
- *   The kernel side of netmap uses two additional fields in the kring:
- *	nr_hwcur is a copy of nr_cur on an NIOCRXSYNC
- *	nr_hwavail is the number of packets available. It is updated
- *		on INTR (inc by the number of new packets arrived)
- *		and on NIOCRXSYNC (decreased by nr_cur - nr_hwcur).
- *
- * DATA OWNERSHIP/LOCKING:
- *	The netmap_ring is owned by the user program and it is only
- *	accessed or modified in the upper half of the kernel during
- *	a system call.
- *
- *	The netmap_kring is only modified by the upper half of the kernel.

- * This header contains the macros used to manipulate netmap structures
- * and packets in userspace. See netmap(4) for more information.
- *
- * The address of the struct netmap_if, say nifp, is computed from the
- * value returned from ioctl(.., NIOCREG, ...) and the mmap region:
- *	ioctl(fd, NIOCREG, &req);
- *	mem = mmap(0, ... );
- *	nifp = NETMAP_IF(mem, req.nr_nifp);
- *		(so simple, we could just do it manually)
- *
- * From there:
- *	struct netmap_ring *NETMAP_TXRING(nifp, index)
- *	struct netmap_ring *NETMAP_RXRING(nifp, index)
- *		we can access ring->nr_cur, ring->nr_avail, ring->nr_flags
- *
- *	ring->slot[i] gives us the i-th slot (we can access
- *		directly plen, flags, bufindex)
- *
- *	char *buf = NETMAP_BUF(ring, index) returns a pointer to
- *		the i-th buffer
- *
- * Since rings are circular, we have macros to compute the next index
- *	i = NETMAP_RING_NEXT(ring, i);
