docs: better docs, mv doxygen to sphinx
This patch refactors the VPP sphinx docs in order to make it easier to consume for external readers as well as VPP developers. It also makes sphinx the single source of documentation, which simplifies maintenance and operation. Most important updates are: - reformat the existing documentation as rst - split RELEASE.md and move it into separate rst files - remove section 'events' - remove section 'archive' - remove section 'related projects' - remove section 'feature by release' - remove section 'Various links' - make (Configuration reference, CLI docs, developer docs) top level items in the list - move 'Use Cases' as part of 'About VPP' - move 'Troubleshooting' as part of 'Getting Started' - move test framework docs into 'Developer Documentation' - add a 'Contributing' section for gerrit, docs and other contributer related infos - deprecate doxygen and test-docs targets - redirect the "make doxygen" target to "make docs" Type: refactor Change-Id: I552a5645d5b7964d547f99b1336e2ac24e7c209f Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com> Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

+
+Getting Started with the debug CLI
+==================================
+
+The VPP network stack comes equipped with a set of commands that are useful
+for debugging.
+
+The easiest way to access the CLI (with proper permissions) is to use the
+vppctl command:
+
+.. code-block:: console
+
+ sudo vppctl <cli-command>
+
+
+The CLI parser matches static keyword strings, eventually invoking an action
+function. Unambiguous partial keyword matching always occurs. The action
+functions consume input until satisfied or until they fail. This model makes
+for easy coding, but does not guarantee useful "help" output. It's up to the
+CLI command writer to add useful help strings.
+
+You can find the source code of CLI commands by searching for instances of the
+``VLIB_CLI_COMMAND`` macro in the code source files.
+
+Please help maintain and improve this document to make and keep these commands
+clear and useful!
+
+.. _debug_telnet_cli:
+
+Debug and Telnet CLI
+--------------------
+
+The debug CLI is enabled with the unix interactive parameter or startup
+configuration option. This causes VPP to start without daemonizing and
+presents a command line interface on the terminal where it is run.
+
+The Telnet CLI is enabled with the ``cli-listen localhost:5002`` option which
+will cause VPP to listen for TCP connections on the localhost address port
+``5002``. A Telnet client can then connect to this port (for example, ``telnet
+localhost 5002``) and will receive a command line prompt.
+
+This configuration will enable both mechanisms:
+
+.. code-block:: console
+
+ unix {
+ interactive
+ cli-listen localhost:5002
+ }
+
+
+The debug CLI can operate in line mode, which may be useful when running
+inside an IDE like Emacs. This is enabled with the option
+``unix cli-line-mode``. Several other options exist that alter how this
+CLI works, see the @ref syscfg section for details.
+
+The CLI starts with a banner graphic (which can be disabled) and a prompt. The
+prompt will typically read ``vpp`` for a release version of VPP and ``DBGvpp#``
+for a development version with debugging enabled, for example:
+
+.. code-block:: console
+
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+ vpp#
+
+
+
+versus:
+
+.. code-block:: console
+
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+ DBGvpp#
+
+
+This prompt can be configured with the ``unix cli-prompt`` setting and the
+banner is disabled with ``unix cli-no-banner``.
+
+.. _cli_features:
+
+CLI features
+------------
+
+The CLI has several editing features that make it easy to use.
+
+- Cursor keys ``left/right`` will move the cursor within a command line;
+ typing will insert at the cursor; erase will erase at the cursor.
+
+- ``Ctrl-left/right`` will search for the start of the next word to
+ the left or right.
+- ``Home/end`` will jump the cursor to the start and end of the line.
+- Cursor keys up/down and ``^P/^N`` iterate through the command history
+ buffer. Lines from the history buffer may be edited. New commands
+ are added to the end of the buffer when executed; though
+ duplicates of the previous command are not added.
+- ``^U`` erases the line contents from the left of the cursor to the
+ start.
+- ``^K`` erases the contents from the cursor to the end.
+- ``^S/^R`` will search the command history forwards or in reverse for
+ a command; start typing for matches to auto complete.
+- ``^L`` will clear the screen (if supported by the terminal) and repaint
+ the prompt and any current line. The cursor position is also
+ retained.
+- The CLI can be closed with the quit command. Alternatively, ``^D`` on
+ an empty input line will also close the session. Closing the debug
+ session will also shutdown VPP.
+
+Output that exceeds the length of a terminal page will be buffered, up to a
+limit.
+
+- ``Space`` or ``page-down`` displays the next page.
+- ``Enter`` or ``down-arrow`` displays the next line.
+- ``Page-up`` goes back a page.
+- ``Up-arrow`` goes up a line.
+- ``Home/end`` jump to the start/end of the buffered output.
+- The key ``q`` quits the pager. ``Space`` and ``enter`` will also quit the
+ pager if the end of the buffer has been reached. \ No newline at end of file

+Create Interfaces Commands
+===========================
+This section contains those interface commands that are associated to creating an interface:
+
+* `Create Host-Interface`_
+* `Create Interface Memif`_
+* `Create Loopback Interface`_
+* `Create Sub-Interfaces`_
+
+.. note:: For a complete list of CLI Debug commands refer to the Debug CLI section of the `Source Code Documents <https://docs.fd.io/vpp/18.07/clicmd.html>`_ .
+
+Create Host-Interface
+++++++++++++++++++++++
+
+.. code-block:: console
+
+ create host-interface name <*ifname*> [*hw-addr <*mac-addr*>]
+
+
+Description
+------------
+
+Create a host interface that will attach to a linux AF_PACKET interface, one side of a veth pair.
+The veth pair must already exist. Once created, a new host interface will exist in VPP with the name
+'host-<*ifname*>', where '<*ifname*>' is the name of the specified veth pair.
+Use the `show interface` command to display host interface details.
+
+This command has the following optional parameters:
+
+ hw-addr <*mac-addr*> - Optional ethernet address, can be in either X:X:X:X:X:X unix or X.X.X cisco format
+
+Example Usage
+-------------
+
+Example of how to create a host interface tied to one side of an existing linux veth pair named vpp1:
+
+ .. code-block:: console
+
+ vpp# create host-interface name vpp1
+
+ host-vpp1
+
+Once the host interface is created, enable the interface using:
+
+ .. code-block:: console
+
+ vpp# set interface state host-vpp1 up
+
+Declaration and Implementation
+-------------------------------
+
+**Declaration:** af_packet_create_command (src/vnet/devices/af_packet/cli.c line 133)
+
+**Implementation:** af_packet_create_command_fn
+
+Create Interface Memif
++++++++++++++++++++++++
+
+.. code-block:: console
+
+ create interface memif [id <*id*>] [socket-id <*socket-id*>] [ring-size <*size*>] [buffer-size <*size*>] [hw-addr <*mac-address*>] <master|slave> [rx-queues <*number*>] [tx-queues <*number*>] [mode ip] [secret <*string*>]
+
+
+Declaration and Implementation
+-------------------------------
+
+**Declaration:** memif_create_command (src/plugins/memif/cli.c line 258)
+
+**Implementation:** memif_create_command_fn
+
+
+Create Loopback Interface
+++++++++++++++++++++++++++
+
+
+Create a loopback interface. Optionally, a MAC Address can be provided. If not provided, de:ad:00:00:00:<*loopId*> will be used.
+
+.. code-block:: console
+
+ create loopback interface [mac <*mac-addr*>] [instance <*instance*>]
+
+
+Example Usage
+--------------
+The following two command syntaxes are equivalent:
+
+ .. code-block:: console
+
+ vpp# loopback create-interface [mac <*mac-addr*>] [instance <*instance*>]
+
+ vpp# create loopback interface [mac <*mac-addr*>] [instance <*instance*>]
+
+Example of how to create a loopback interface:
+
+ .. code-block:: console
+
+ vpp# create loopback interface
+
+Declaration and Implementation
+-------------------------------
+
+**Declaration:** create_loopback_interface_command (src/vnet/ethernet/interface.c line 879)
+
+**Implementation:** create_simulated_ethernet_interfaces
+
+
+Create Sub-Interfaces
+++++++++++++++++++++++
+
+This command is used to add VLAN IDs to interfaces, also known as
+subinterfaces. The primary input to this command is the *interface*
+and *subId* (subinterface Id) parameters. If no additional VLAN ID is
+provide, the VLAN ID is assumed to be the *subId*. The VLAN ID and
+*subId* can be different, but this is not recommended.
+
+This command has several variations:
+
+- **create sub-interfaces** <*interface*> <*subId*> - Create a subinterface
+ to process packets with a given 802.1q VLAN ID (same value as the
+ *subId*).
+- **create sub-interfaces** <*interface*> <*subId*> default - Adding the
+ *default* parameter indicates that packets with VLAN IDs that do
+ not match any other subinterfaces should be sent to this
+ subinterface.
+- **create sub-interfaces** <*interface*> <*subId*> untagged - Adding the
+ *untagged* parameter indicates that packets no VLAN IDs should be
+ sent to this subinterface.
+- **create sub-interfaces** <*interface*> <*subId*>-<*subId*> - Create a
+ range of subinterfaces to handle a range of VLAN IDs.
+- **create sub-interfaces** <*interface*> <*subId*> dot1q|dot1ad <*vlanId*>|any
+ [exact-match] - Use this command to explicitly specify the outer VLAN ID,
+ or to make the VLAN ID different from the *subId*.
+- **create sub-interfaces** <*interface*> <*subId*> dot1q|dot1ad <*vlanId*>|any
+ inner-dot1q <*vlanId*>|any [exact-match] - Use this command to
+ specify the outer VLAN ID and the inner VLAN ID.
+
+When *dot1q* or *dot1ad* is explicitly entered, subinterfaces can be
+configured as either *exact-match* or *non-exact match*. *Non-exact match* is
+the CLI default. If *exact-match* is specified, packets must have the
+same number of VLAN tags as the configuration. For *non-exact-match*,
+packets must at least that number of tags. L3 (routed) interfaces must
+be configured as exact-match. L2 interfaces are typically configured as
+non-exact-match. If *dot1q* or *dot1ad* is NOT entered, then the
+default behavior is *exact-match*.
+
+Use the **show interface** command to display all subinterfaces.
+
+Summary/Usage
+-------------
+
+.. code-block:: shell
+
+ create sub-interfaces <interface> {<subId> [default|untagged]} | {<subId>-<subId>} | {<subId> dot1q|dot1ad <vlanId>|any [inner-dot1q <vlanId>|any] [exact-match]}
+
+Example Usage
+--------------
+
+Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11
+
+The previous example is shorthand and is equivalent to:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match
+
+Example of how to create a subinterface number that is different from the VLAN ID:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100
+
+Examples of how to create q-in-q and q-in-any subinterfaces:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
+ vpp# create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
+
+Examples of how to create dot1ad interfaces:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11
+ vpp# create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200
+
+Examples of *exact-match* versus non-exact match. A packet with outer VLAN 100 and inner VLAN 200 would match this interface, because the default is non-exact match:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100
+
+However, the same packet would NOT match this interface because *exact-match* is specified and only one VLAN is configured, but packet contains two VLANs:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match
+
+Example of how to created a subinterface to process untagged packets:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 5 untagged
+
+Example of how to created a subinterface to process any packet with a VLAN ID that does not match any other subinterface:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 7 default
+
+When subinterfaces are created, they are in the down state. Example of how to enable a newly created subinterface:
+
+.. code-block:: console
+
+ vpp# set interface GigabitEthernet2/0/0.7 up
+

+ Documents <https://docs.fd.io/vpp/18.07/clicmd.html>`__ .
+
+Set Interface IP Address
+========================
+
+.. code:: console
+
+ set interface ip address [del] <*interface*> <*ip-addr*>/<*mask*> | [all]
+
+Add an IP Address to an interface or remove and IP Address from an
+interface. The IP Address can be an IPv4 or an IPv6 address. Interfaces
+may have multiple IPv4 and IPv6 addresses. There is no concept of
+primary vs. secondary interface addresses; they're just addresses.
+
+To display the addresses associated with a given interface, use the
+command **show interface address** <*interface*>.
+
+.. note::
+
+ The debug CLI does not enforce classful mask-width / addressing
+ constraints.
+
+Example Usage
+-------------
+
+An example of how to add an IPv4 address to an interface:
+
+.. code:: console
+
+ vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24
+
+An example of how to add an IPv6 address to an interface:
+
+.. code:: console
+
+ vpp# set interface ip address GigabitEthernet2/0/0 ::a:1:1:0:7/126
+
+To delete a specific interface ip address:
+
+.. code:: console
+
+ vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24 del
+
+To delete all interfaces addresses (IPv4 and IPv6):
+
+.. code:: console
+
+ vpp# set interface ip address GigabitEthernet2/0/0 del all

+
+Set Interface L2 Bridge
+=======================
+
+.. code:: console
+
+ set interface l2 bridge <*interface*> <*bridge-domain-id*> [bvi|uu-fwd]
+ [shg]
+
+Use this command put an interface into Layer 2 bridge domain. If a
+bridge-domain with the provided bridge-domain-id does not exist, it will
+be created. Interfaces in a bridge-domain forward packets to other
+interfaces in the same bridge-domain based on destination mac address.
+To remove an interface from a the Layer 2 bridge domain, put the
+interface in a different mode, for example Layer 3 mode.
+
+Optionally, an interface can be added to a Layer 2 bridge-domain as a
+Bridged Virtual Interface (bvi). Only one interface in a Layer 2
+bridge-domain can be a bvi.
+
+Optionally, a split-horizon group can also be specified. This defaults
+to 0 if not specified.
+
+.. _example-usage-1:
+
+Example Usage
+-------------
+
+Example of how to configure a Layer 2 bridge-domain with three
+interfaces (where 200 is the bridge-domain-id):
+
+.. code:: console
+
+ vpp# set interface l2 bridge GigabitEthernet0/8/0.200 200
+
+This interface is added a BVI interface:
+
+.. code:: console
+
+ vpp# set interface l2 bridge GigabitEthernet0/9/0.200 200 bvi
+
+This interface also has a split-horizon group of 1 specified:
+
+.. code:: console
+
+ vpp# set interface l2 bridge GigabitEthernet0/a/0.200 200 1
+
+Example of how to remove an interface from a Layer2 bridge-domain:
+
+.. code:: console
+
+ vpp# set interface l3 GigabitEthernet0/a/0.200

+
+Set Interface MTU
+=================
+
+.. code:: shell
+
+ set interface mtu [packet|ip4|ip6|mpls] <value> <interface>
+
+Set Interface Promiscuous
+=========================
+
+.. code:: shell
+
+ set interface promiscuous [on|off] <interface>.
+
+.. _setintstate:
+
+Set Interface State
+===================
+
+This command is used to change the admin state (up/down) of an
+interface.
+
+If an interface is down, the optional *punt* flag can also be set. The
+*punt* flag implies the interface is disabled for forwarding but punt
+all traffic to slow-path. Use the *enable* flag to clear *punt* flag
+(interface is still down).
+
+.. code:: shell
+
+ set interface state <interface> [up|down|punt|enable].
+
+.. _example-usage-2:
+
+Example Usage
+-------------
+
+Example of how to configure the admin state of an interface to **up**:
+
+.. code:: console
+
+ vpp# set interface state GigabitEthernet2/0/0 up
+
+Example of how to configure the admin state of an interface to **down**:
+
+.. code:: console
+
+ vpp# set interface state GigabitEthernet2/0/0 down
