+Introduction
+------------
+CAIF is a MUX protocol used by ST-Ericsson cellular modems for
+communication between Modem and host. The host processes can open virtual AT
+channels, initiate GPRS Data connections, Video channels and Utility Channels.
+The Utility Channels are general purpose pipes between modem and host.
+
+ST-Ericsson modems support a number of transports between modem
+and host. Currently, UART and Loopback are available for Linux.
+
+
+Architecture:
+------------
+The implementation of CAIF is divided into:
+* CAIF Socket Layer, Kernel API, and Net Device.
+* CAIF Core Protocol Implementation
+* CAIF Link Layer, implemented as NET devices.

+
+Using the Kernel API
+----------------------
+The Kernel API is used for accessing CAIF channels from the
+kernel.
+The user of the API has to implement two callbacks for receive
+and control.
+The receive callback gives a CAIF packet as a SKB. The control
+callback will
+notify of channel initialization complete, and flow-on/flow-
+off.
+
+
+ struct caif_device caif_dev = {
+ .caif_config = {

+ };

+===========================
+===========================
+
+CAIF Core Protocol Layer
+=========================================
+
+CAIF Core layer implements the CAIF protocol as defined by ST-Ericsson.
+It implements the CAIF protocol stack in a layered approach, where
+each layer described in the specification is implemented as a separate layer.
+The architecture is inspired by the design patterns "Protocol Layer" and
+"Protocol Packet".
+
+== CAIF structure ==
+The Core CAIF implementation contains:
+ - Simple implementation of CAIF.
+ - Layered architecture (a la Streams), each layer in the CAIF
+ specification is implemented in a separate c-file.
+ - Clients must implement PHY layer to access physical HW
+ with receive and transmit functions.
+ - Clients must call configuration function to add PHY layer.
+ - Clients must implement CAIF layer to consume/produce
+ CAIF payload with receive and transmit functions.
+ - Clients must call configuration function to add and connect the
+ Client layer.
+ - When receiving / transmitting CAIF Packets (cfpkt), ownership is passed
+ to the called function (except for framing layers' receive functions
+ or if a transmit function returns an error, in which case the caller
+ must free the packet).
+
+Layered Architecture
+--------------------
+The CAIF protocol can be divided into two parts: Support functions and Protocol
+Implementation. The support functions include:
+
+ - CFPKT CAIF Packet. Implementation of CAIF Protocol Packet. The
+ CAIF Packet has functions for creating, destroying and adding content
+ and for adding/extracting header and trailers to protocol packets.
+
+ - CFLST CAIF list implementation.
+
+ - CFGLUE CAIF Glue. Contains OS Specifics, such as memory
+ allocation, endianness, etc.
+
+The CAIF Protocol implementation contains:
+
+ - CFCNFG CAIF Configuration layer. Configures the CAIF Protocol
+ Stack and provides a Client interface for adding Link-Layer and
+ Driver interfaces on top of the CAIF Stack.
+
+ - CFCTRL CAIF Control layer. Encodes and Decodes control messages
+ such as enumeration and channel setup. Also matches request and
+ response messages.
+
+ - CFSERVL General CAIF Service Layer functionality; handles flow
+ control and remote shutdown requests.
+
+ - CFVEI CAIF VEI layer. Handles CAIF AT Channels on VEI (Virtual
+ External Interface). This layer encodes/decodes VEI frames.
+
+ - CFDGML CAIF Datagram layer. Handles CAIF Datagram layer (IP
+ traffic), encodes/decodes Datagram frames.
+
+ - CFMUX CAIF Mux layer. Handles multiplexing between multiple
+ physical bearers and multiple channels such as VEI, Datagram, etc.
+ The MUX keeps track of the existing CAIF Channels and
+ Physical Instances and selects the apropriate instance based
+ on Channel-Id and Physical-ID.
+
+ - CFFRML CAIF Framing layer. Handles Framing i.e. Frame length
+ and frame checksum.
+
+ - CFSERL CAIF Serial layer. Handles concatenation/split of frames
+ into CAIF Frames with correct length.
+
+
+

+ | Config |
+ | CFCNFG |

+ !
+ +---------+ +---------+ +---------+
+ | AT | | Control | | Datagram|
+ | CFVEIL | | CFCTRL | | CFDGML |

+ | Framing | | Framing |
+ +---------+ +---------+
+ ! !
+ +---------+ +---------+
+ | | | Serial |
+ | | | CFSERL |
+ +---------+ +---------+
+
+
+In this layered approach the following "rules" apply.
+ - All layers embed the same structure "struct cflayer"
+ - A layer does not depend on any other layer's private data.
+ - Layers are stacked by setting the pointers
+ layer->up , layer->dn
+ - In order to send data upwards, each layer should do
+ layer->up->receive(layer->up, packet);
+ - In order to send data downwards, each layer should do
+ layer->dn->transmit(layer->dn, packet);
+
+
+Linux Driver Implementation
+===========================
+
+Linux GPRS Net Device and CAIF socket are implemented on top of the
+CAIF Core protocol. The Net device and CAIF socket have an instance of
+'struct cflayer', just like the CAIF Core protocol stack.
+Net device and Socket implement the 'receive()' function defined by
+'struct cflayer', just like the rest of the CAIF stack. In this way, transmit and
+receive of packets is handled as by the rest of the layers: the 'dn->transmit()'
+function is called in order to transmit data.
+
+The layer on top of the CAIF Core implementation is
+sometimes referred to as the "Client layer".
+
+
+Configuration of Link Layer
+---------------------------
+The Link Layer is implemented as Linux net devices (struct net_device).
+Payload handling and registration is done using standard Linux mechanisms.
+
+The CAIF Protocol relies on a loss-less link layer without implementing
+retransmission. This implies that packet drops must not happen.
+Therefore a flow-control mechanism is implemented where the physical
+interface can initiate flow stop for all CAIF Channels.

+
+=== Start ===
+If you have compiled CAIF for modules do:
+
+$modprobe crc_ccitt
+$modprobe caif
+$modprobe caif_socket
+$modprobe chnl_net
+
+
+=== Preparing the setup with a STE modem ===
+
+If you are working on integration of CAIF you should make sure
+that the kernel is built with module support.
+
+There are some things that need to be tweaked to get the host TTY correctly
+set up to talk to the modem.
+Since the CAIF stack is running in the kernel and we want to use the existing
+TTY, we are installing our physical serial driver as a line discipline above
+the TTY device.
+
+To achieve this we need to install the N_CAIF ldisc from user space.
+The benefit is that we can hook up to any TTY.
+
+The use of Start-of-frame-extension (STX) must also be set as
+module parameter "ser_use_stx".
+
+Normally Frame Checksum is always used on UART, but this is also provided as a
+module parameter "ser_use_fcs".
+
+$ modprobe caif_serial ser_ttyname=/dev/ttyS0 ser_use_stx=yes
+$ ifconfig caif_ttyS0 up
+
+PLEASE NOTE: There is a limitation in Android shell.
+ It only accepts one argument to insmod/modprobe!
+
+=== Trouble shooting ===
+
+There are debugfs parameters provided for serial communication.
+/sys/kernel/debug/caif_serial/<tty-name>/
+
+* ser_state: Prints the bit-mask status where
+ - 0x02 means SENDING, this is a transient state.
+ - 0x10 means FLOW_OFF_SENT, i.e. the previous frame has not been sent
+ and is blocking further send operation. Flow OFF has been propagated
+ to all CAIF Channels using this TTY.
+
+* tty_status: Prints the bit-mask tty status information
+ - 0x01 - tty->warned is on.
+ - 0x02 - tty->low_latency is on.
+ - 0x04 - tty->packed is on.
+ - 0x08 - tty->flow_stopped is on.
+ - 0x10 - tty->hw_stopped is on.
+ - 0x20 - tty->stopped is on.
+
+* last_tx_msg: Binary blob Prints the last transmitted frame.
+ This can be printed with
+ $od --format=x1 /sys/kernel/debug/caif_serial/<tty>/last_rx_msg.
+ The first two tx messages sent look like this. Note: The initial
+ byte 02 is start of frame extension (STX) used for re-syncing
+ upon errors.

+ 0000000 02 05 00 00 03 01 d2 02

+ Length(2)| | | | |
+ Control Channel(1)
+ Command:Channel Setup(1)
+ Channel Type(1)
+ Priority and Link-ID(1)
+ Endpoint(1)
+ Checksum(2)
+
+* last_rx_msg: Prints the last transmitted frame.
+ The RX messages for LinkSetup look almost identical but they have the
+ bit 0x20 set in the command bit, and Channel Setup has added one byte
+ before Checksum containing Channel ID.
+ NOTE: Several CAIF Messages might be concatenated. The maximum debug
+ buffer size is 128 bytes.
+
+== Error Scenarios:
+- last_tx_msg contains channel setup message and last_rx_msg is empty ->
+ The host seems to be able to send over the UART, at least the CAIF ldisc get
+ notified that sending is completed.
+
+- last_tx_msg contains enumeration message and last_rx_msg is empty ->
+ The host is not able to send the message from UART, the tty has not been
+ able to complete the transmit operation.
+
+- if /sys/kernel/debug/caif_serial/<tty>/tty_status is non-zero there
+ might be problems transmitting over UART.
+ E.g. host and modem wiring is not correct you will typically see
+ tty_status = 0x10 (hw_stopped) and ser_state = 0x10 (FLOW_OFF_SENT).
+ You will probably see the enumeration message in last_tx_message
+ and empty last_rx_message.

+L2TPv3 PPP pseudowires.

+Netlink sockets for L2TPv3 configuration management.
+
+History
+=======
+
+The original pppol2tp driver was introduced in 2.6.23 and provided
+L2TPv2 functionality (rfc2661). L2TPv2 is used to tunnel one or more PPP
+sessions over a UDP tunnel.
+
+L2TPv3 (rfc3931) changes the protocol to allow different frame types
+to be passed over an L2TP tunnel by moving the PPP-specific parts of
+the protocol out of the core L2TP packet headers. Each frame type is
+known as a pseudowire type. Ethernet, PPP, HDLC, Frame Relay and ATM
+pseudowires for L2TP are defined in separate RFC standards. Another
+change for L2TPv3 is that it can be carried directly over IP with no
+UDP header (UDP is optional). It is also possible to create static
+unmanaged L2TPv3 tunnels manually without a control protocol
+(userspace daemon) to manage them.
+
+To support L2TPv3, the original pppol2tp driver was split up to
+separate the L2TP and PPP functionality. Existing L2TPv2 userspace
+apps should be unaffected as the original pppol2tp sockets API is
+retained. L2TPv3, however, uses netlink to manage L2TPv3 tunnels and
+sessions.
Design
======
-The PPPoL2TP driver, drivers/net/pppol2tp.c, provides a mechanism by
-which PPP frames carried through an L2TP session are passed through
-the kernel's PPP subsystem. The standard PPP daemon, pppd, handles all
-PPP interaction with the peer. PPP network interfaces are created for
-each local PPP endpoint.
+The L2TP protocol separates control and data frames. The L2TP kernel
+drivers handle only L2TP data frames; control frames are always
+handled by userspace. L2TP control frames carry messages between L2TP
+clients/servers and are used to setup / teardown tunnels and
+sessions. An L2TP client or server is implemented in userspace.
-The L2TP protocol http://www.faqs.org/rfcs/rfc2661.html defines L2TP
-control and data frames. L2TP control frames carry messages between
-L2TP clients/servers and are used to setup / teardown tunnels and
-sessions. An L2TP client or server is implemented in userspace and
-will use a regular UDP socket per tunnel. L2TP data frames carry PPP
-frames, which may be PPP control or PPP data. The kernel's PPP
+Each L2TP tunnel is implemented using a UDP or L2TPIP socket; L2TPIP
+provides L2TPv3 IP encapsulation (no UDP) and is implemented using a
+new l2tpip socket family. The tunnel socket is typically created by
+userspace, though for unmanaged L2TPv3 tunnels, the socket can also be
+created by the kernel. Each L2TP session (pseudowire) gets a network
+interface instance. In the case of PPP, these interfaces are created
+indirectly by pppd using a pppol2tp socket. In the case of ethernet,
+the netdevice is created upon a netlink request to create an L2TPv3
+ethernet pseudowire.
+
+For PPP, the PPPoL2TP driver, net/l2tp/l2tp_ppp.c, provides a
+mechanism by which PPP frames carried through an L2TP session are
+passed through the kernel's PPP subsystem. The standard PPP daemon,
+pppd, handles all PPP interaction with the peer. PPP network
+interfaces are created for each local PPP endpoint. The kernel's PPP
subsystem arranges for PPP control frames to be delivered to pppd,
while data frames are forwarded as usual.
+For ethernet, the L2TPETH driver, net/l2tp/l2tp_eth.c, implements a
+netdevice driver, managing virtual ethernet devices, one per
+pseudowire. These interfaces can be managed using standard Linux tools
+such as "ip" and "ifconfig". If only IP frames are passed over the
+tunnel, the interface can be given an IP addresses of itself and its
+peer. If non-IP frames are to be passed over the tunnel, the interface

to retrieve tunnel and session statistics from the kernel using the
PPPoX socket of the appropriate tunnel or session.
+For L2TPv3, userspace must use the netlink API defined in
+include/linux/l2tp.h to manage tunnel and session contexts. The
+general procedure to create a new L2TP tunnel with one session is:-
+
+1. Open a GENL socket using L2TP_GENL_NAME for configuring the kernel
+ using netlink.
+
+2. Create a UDP or L2TPIP socket for the tunnel.
+
+3. Create a new L2TP tunnel using a L2TP_CMD_TUNNEL_CREATE
+ request. Set attributes according to desired tunnel parameters,
+ referencing the UDP or L2TPIP socket created in the previous step.
+
+4. Create a new L2TP session in the tunnel using a
+ L2TP_CMD_SESSION_CREATE request.
+
+The tunnel and all of its sessions are closed when the tunnel socket
+is closed. The netlink API may also be used to delete sessions and
+tunnels. Configuration and status info may be set or read using netlink.
+
+The L2TP driver also supports static (unmanaged) L2TPv3 tunnels. These
+are where there is no L2TP control message exchange with the peer to
+setup the tunnel; the tunnel is configured manually at each end of the
+tunnel. There is no need for an L2TP userspace application in this
+case -- the tunnel socket is created by the kernel and configured
+using parameters sent in the L2TP_CMD_TUNNEL_CREATE netlink
+request. The "ip" utility of iproute2 has commands for managing static
+L2TPv3 tunnels; do "ip l2tp help" for more information.

+Some commercial L2TP products support unmanaged L2TPv3 ethernet

+To create an L2TPv3 ethernet pseudowire between local host 192.168.1.1

+# ifconfig -a
+# ip addr add 10.5.1.2/32 peer 10.5.1.1/32 dev l2tpeth0
+# ifconfig l2tpeth0 up
+
+Choose IP addresses to be the address of a local IP interface and that
+of the remote system. The IP addresses of the l2tpeth0 interface can be
+anything suitable.
+
+Repeat the above at the peer, with ports, tunnel/session ids and IP
+addresses reversed. The tunnel and session IDs can be any non-zero
+32-bit number, but the values must be reversed at the peer.

+Internal Implementation
+=======================
-The PPPoL2TP driver was developed as part of the OpenL2TP project by
+The driver keeps a struct l2tp_tunnel context per L2TP tunnel and a
+struct l2tp_session context for each session. The l2tp_tunnel is
+always associated with a UDP or L2TP/IP socket and keeps a list of
+sessions in the tunnel. The l2tp_session context keeps kernel state
+about the session. It has private data which is used for data specific
+to the session type. With L2TPv2, the session always carried PPP
+traffic. With L2TPv3, the session can also carry ethernet frames
+(ethernet pseudowire) or other data types such as ATM, HDLC or Frame
+Relay.
+
+When a tunnel is first opened, the reference count on the socket is
+increased using sock_hold(). This ensures that the kernel socket
+cannot be removed while L2TP's data structures reference it.
+
+Some L2TP sessions also have a socket (PPP pseudowires) while others
+do not (ethernet pseudowires). We can't use the socket reference count
+as the reference count for session contexts. The L2TP implementation
+therefore has its own internal reference counts on the session
+contexts.
+
+To Do
+=====
+
+Add L2TP tunnel switching support. This would route tunneled traffic
+from one L2TP tunnel into another. Specified in
+http://tools.ietf.org/html/draft-ietf-l2tpext-tunnel-switching-08
+
+Add L2TPv3 VLAN pseudowire support.
+
+Add L2TPv3 IP pseudowire support.
+
+Add L2TPv3 ATM pseudowire support.

+The L2TP drivers were developed as part of the OpenL2TP project by
Katalix Systems Ltd. OpenL2TP is a full-featured L2TP client / server,
designed from the ground up to have the L2TP datapath in the
kernel. The project also implemented the pppol2tp plugin for pppd
which allows pppd to use the kernel driver. Details can be found at

-/* This driver handles only L2TP data frames; control frames are handled by a
- * userspace application.
- *
- * To send data in an L2TP session, userspace opens a PPPoL2TP socket and
- * attaches it to a bound UDP socket with local tunnel_id / session_id and
- * peer tunnel_id / session_id set. Data can then be sent or received using
- * regular socket sendmsg() / recvmsg() calls. Kernel parameters of the socket
- * can be read or modified using ioctl() or [gs]etsockopt() calls.
- *
- * When a PPPoL2TP socket is connected with local and peer session_id values
- * zero, the socket is treated as a special tunnel management socket.
- *
- * Here's example userspace code to create a socket for sending/receiving data
- * over an L2TP session:-
- *
- * struct sockaddr_pppol2tp sax;
- * int fd;
- * int session_fd;
- *
- * fd = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
- *
- * sax.sa_family = AF_PPPOX;
- * sax.sa_protocol = PX_PROTO_OL2TP;
- * sax.pppol2tp.fd = tunnel_fd; // bound UDP socket
- * sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
- * sax.pppol2tp.addr.sin_port = addr->sin_port;
- * sax.pppol2tp.addr.sin_family = AF_INET;
- * sax.pppol2tp.s_tunnel = tunnel_id;
- * sax.pppol2tp.s_session = session_id;
- * sax.pppol2tp.d_tunnel = peer_tunnel_id;
- * sax.pppol2tp.d_session = peer_session_id;
- *
- * session_fd = connect(fd, (struct sockaddr *)&sax, sizeof(sax));
- *
- * A pppd plugin that allows PPP traffic to be carried over L2TP using
- * this driver is available from the OpenL2TP project at
- * http://openl2tp.sourceforge.net.

+ * Adaptive Noise Immunity (ANI) controls five noise immunity parameters

+ * The parameters are:
+ * - "noise immunity"
+ * - "spur immunity"
+ * - "firstep level"
+ * - "OFDM weak signal detection"
+ * - "CCK weak signal detection"
+ *
+ * Basically we look at the amount of ODFM and CCK timing errors we get and then
+ * raise or lower immunity accordingly by setting one or more of these
+ * parameters.
+ * Newer chipsets have PHY error counters in hardware which will generate a MIB
+ * interrupt when they overflow. Older hardware has too enable PHY error frames
+ * by setting a RX flag and then count every single PHY error. When a specified
+ * threshold of errors has been reached we will raise immunity.
+ * Also we regularly check the amount of errors and lower or raise immunity as
+ * necessary.

-/**
- * DOC: Programming Atheros 802.11n analog front end radios
- *
- * AR5416 MAC based PCI devices and AR518 MAC based PCI-Express
- * devices have either an external AR2133 analog front end radio for single
- * band 2.4 GHz communication or an AR5133 analog front end radio for dual
- * band 2.4 GHz / 5 GHz communication.
- *
- * All devices after the AR5416 and AR5418 family starting with the AR9280
- * have their analog front radios, MAC/BB and host PCIe/USB interface embedded
- * into a single-chip and require less programming.
- *
- * The following single-chips exist with a respective embedded radio:
- *
- * AR9280 - 11n dual-band 2x2 MIMO for PCIe

+ *
+ * VO 0
+ * VI 1
+ * BE 2
+ * BK 3
+ *
+ *
+ * Regular (not A-MPDU) frames are put into hardware queues corresponding
+ * to the FIFOs, see comments in iwl-prph.h. Aggregated frames get their
+ * own queue per aggregation session (RA/TID combination), such queues are
+ * set up to map into FIFOs too, for which we need an AC->FIFO mapping. In
+ * order to map frames to the right queue, we also need an AC->hw queue
+ * mapping. This is implemented here.
+ *
+ * Due to the way hw queues are set up (by the hw specific modules like
+ * iwl-4965.c, iwl-5000.c etc.), the AC->hw queue mapping is the identity
+ * mapping.

+ Layer Two Tunneling Protocol
+
+ From RFC 2661 <http://www.ietf.org/rfc/rfc2661.txt>.
+
+ L2TP facilitates the tunneling of packets across an
+ intervening network in a way that is as transparent as
+ possible to both end-users and applications.
+
+ L2TP is often used to tunnel PPP traffic over IP
+ tunnels. One IP tunnel may carry thousands of individual PPP
+ connections. L2TP is also used as a VPN protocol, popular
+ with home workers to connect to their offices.
+
+ L2TPv3 allows other protocols as well as PPP to be carried
+ over L2TP tunnels. L2TPv3 is defined in RFC 3931
+ <http://www.ietf.org/rfc/rfc3931.txt>.
+
+ The kernel component handles only L2TP data packets: a
+ userland daemon handles L2TP the control protocol (tunnel
+ and session setup). One such daemon is OpenL2TP
+ (http://openl2tp.org/).
+
+ If you don't need L2TP, say N. To compile all L2TP code as
+ modules, choose M here.

+ Layer Two Tunneling Protocol Version 3
+
+ From RFC 3931 <http://www.ietf.org/rfc/rfc3931.txt>.
+
+ The Layer Two Tunneling Protocol (L2TP) provides a dynamic
+ mechanism for tunneling Layer 2 (L2) "circuits" across a
+ packet-oriented data network (e.g., over IP). L2TP, as
+ originally defined in RFC 2661, is a standard method for
+ tunneling Point-to-Point Protocol (PPP) [RFC1661] sessions.
+ L2TP has since been adopted for tunneling a number of other
+ L2 protocols, including ATM, Frame Relay, HDLC and even raw
+ ethernet frames.
+
+ If you are connecting to L2TPv3 equipment, or you want to
+ tunnel raw ethernet frames using L2TP, say Y here. If
+ unsure, say N.
+
+config L2TP_IP
+ tristate "L2TP IP encapsulation for L2TPv3"
+ depends on L2TP_V3
+ help
+ Support for L2TP-over-IP socket family.
+
+ The L2TPv3 protocol defines two possible encapsulations for
+ L2TP frames, namely UDP and plain IP (without UDP). This
+ driver provides a new L2TPIP socket family with which
+ userspace L2TPv3 daemons may create L2TP/IP tunnel sockets
+ when UDP encapsulation is not required. When L2TP is carried
+ in IP packets, it used IP protocol number 115, so this port
+ must be enabled in firewalls.
+
+ To compile this driver as a module, choose M here. The module
+ will be called l2tp_ip.
+
+config L2TP_ETH
+ tristate "L2TP ethernet pseudowire support for L2TPv3"
+ depends on L2TP_V3
+ help
+ Support for carrying raw ethernet frames over L2TPv3.
+
+ From RFC 4719 <http://www.ietf.org/rfc/rfc4719.txt>.
+
+ The Layer 2 Tunneling Protocol, Version 3 (L2TPv3) can be
+ used as a control protocol and for data encapsulation to set
+ up Pseudowires for transporting layer 2 Packet Data Units
+ across an IP network [RFC3931].
+
+ This driver provides an ethernet virtual interface for each
+ L2TP ethernet pseudowire instance. Standard Linux tools may
+ be used to assign an IP address to the local virtual
+ interface, or add the interface to a bridge.
+
+ If you are using L2TPv3, you will almost certainly want to
+ enable this option.
+
+ To compile this driver as a module, choose M here. The module
+ will be called l2tp_eth.

+ * Linux PPP over L2TP (PPPoX/PPPoL2TP) Sockets

+ * PPPoX --- Generic PPP encapsulation socket family
+ * PPPoL2TP --- PPP over L2TP (RFC 2661)

+ * Version: 2.0.0
+ *

+
+/* This driver handles only L2TP data frames; control frames are handled by a
+ * userspace application.
+ *
+ * To send data in an L2TP session, userspace opens a PPPoL2TP socket and
+ * attaches it to a bound UDP socket with local tunnel_id / session_id and
+ * peer tunnel_id / session_id set. Data can then be sent or received using
+ * regular socket sendmsg() / recvmsg() calls. Kernel parameters of the socket
+ * can be read or modified using ioctl() or [gs]etsockopt() calls.
+ *
+ * When a PPPoL2TP socket is connected with local and peer session_id values
+ * zero, the socket is treated as a special tunnel management socket.
+ *
+ * Here's example userspace code to create a socket for sending/receiving data
+ * over an L2TP session:-
+ *
+ * struct sockaddr_pppol2tp sax;
+ * int fd;
+ * int session_fd;
+ *
+ * fd = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
+ *
+ * sax.sa_family = AF_PPPOX;
+ * sax.sa_protocol = PX_PROTO_OL2TP;
+ * sax.pppol2tp.fd = tunnel_fd; // bound UDP socket
+ * sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
+ * sax.pppol2tp.addr.sin_port = addr->sin_port;
+ * sax.pppol2tp.addr.sin_family = AF_INET;
+ * sax.pppol2tp.s_tunnel = tunnel_id;
+ * sax.pppol2tp.s_session = session_id;
+ * sax.pppol2tp.d_tunnel = peer_tunnel_id;
+ * sax.pppol2tp.d_session = peer_session_id;
+ *
+ * session_fd = connect(fd, (struct sockaddr *)&sax, sizeof(sax));
+ *
+ * A pppd plugin that allows PPP traffic to be carried over L2TP using
+ * this driver is available from the OpenL2TP project at
+ * http://openl2tp.sourceforge.net.
