-/* bionet.c     BioNet-100 device driver for linux68k.
- *
- * Version:	@(#)bionet.c	1.0	02/06/96
- *
- * Author:	Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and		Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- * Some changes in bionet_poll_rx by Karl-Heinz Lohner
- *
-	What is it ?
-	------------
-	This driver controls the BIONET-100 LAN-Adapter which connects
-	an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
-	This version can be compiled as a loadable module (See the
-	compile command at the bottom of this file).
-	At load time, you can optionally set the debugging level and the
-	fastest response time on the command line of 'insmod'.
-
-	'bionet_debug'
-		controls the amount of diagnostic messages:
-	  0  : no messages
-	  >0 : see code for meaning of printed messages
-
-	'bionet_min_poll_time' (always >=1)
-		gives the time (in jiffies) between polls. Low values
-		increase the system load (beware!)
-
-	When loaded, a net device with the name 'bio0' becomes available,
-	which can be controlled with the usual 'ifconfig' command.
-
-	It is possible to compile this driver into the kernel like other
-	(net) drivers. For this purpose, some source files (e.g. config-files
-	makefiles, Space.c) must be changed accordingly. (You may refer to
-	other drivers how to do it.) In this case, the device will be detected
-	at boot time and (probably) appear as 'eth0'.
-
-	This code is based on several sources:
-	- The driver code for a parallel port ethernet adapter by
-	  Donald Becker (see file 'atp.c' from the PC linux distribution)
-	- The ACSI code by Roman Hodek for the ATARI-ACSI harddisk support
-	  and DMA handling.
-	- Very limited information about moving packets in and out of the
-	  BIONET-adapter from the TCP package for TOS by BioData GmbH.
-
-	Theory of Operation
-	-------------------
-	Because the ATARI DMA port is usually shared between several
-	devices (eg. harddisk, floppy) we cannot block the ACSI bus
-	while waiting for interrupts. Therefore we use a polling mechanism
-	to fetch packets from the adapter. For the same reason, we send
-	packets without checking that the previous packet has been sent to
-	the LAN. We rely on the higher levels of the networking code to detect
-	missing packets and resend them.
-
-	Before we access the ATARI DMA controller, we check if another
-	process is using the DMA. If not, we lock the DMA, perform one or
-	more packet transfers and unlock the DMA before returning.
-	We do not use 'stdma_lock' unconditionally because it is unclear
-	if the networking code can be set to sleep, which will happen if
-	another (possibly slow) device is using the DMA controller.
-
-	The polling is done via timer interrupts which periodically
-	'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
-	between polls varies depending on an estimate of the net activity.
-	The allowed range is given by the variable 'bionet_min_poll_time'
-	for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
-	for the higher (slowest) limit.
-
-	Whenever a packet arrives, we switch to fastest response by setting
-	the polling time to its lowest limit. If the following poll fails,
-	because no packets have arrived, we increase the time for the next
-	poll. When the net activity is low, the polling time effectively
-	stays at its maximum value, resulting in the lowest load for the
-	machine.

-/* atari_pamsnet.c     PAMsNet device driver for linux68k.
- *
- * Version:	@(#)PAMsNet.c	0.2ß	03/31/96
- *
- * Author:  Torsten Lang <Torsten.Lang@ap.physik.uni-giessen.de>
- *                       <Torsten.Lang@jung.de>
- *
- * This driver is based on my driver PAMSDMA.c for MiNT-Net and
- * on the driver bionet.c written by
- *          Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and      Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
-	What is it ?
-	------------
-	This driver controls the PAMsNet LAN-Adapter which connects
-	an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
-	This version can be compiled as a loadable module (See the
-	compile command at the bottom of this file).
-	At load time, you can optionally set the debugging level and the
-	fastest response time on the command line of 'insmod'.
-
-	'pamsnet_debug'
-		controls the amount of diagnostic messages:
-	  0  : no messages
-	  >0 : see code for meaning of printed messages
-
-	'pamsnet_min_poll_time' (always >=1)
-		gives the time (in jiffies) between polls. Low values
-		increase the system load (beware!)
-
-	When loaded, a net device with the name 'eth?' becomes available,
-	which can be controlled with the usual 'ifconfig' command.
-
-	It is possible to compile this driver into the kernel like other
-	(net) drivers. For this purpose, some source files (e.g. config-files
-	makefiles, Space.c) must be changed accordingly. (You may refer to
-	other drivers how to do it.) In this case, the device will be detected
-	at boot time and (probably) appear as 'eth0'.
-
-	Theory of Operation
-	-------------------
-	Because the ATARI DMA port is usually shared between several
-	devices (eg. harddisk, floppy) we cannot block the ACSI bus
-	while waiting for interrupts. Therefore we use a polling mechanism
-	to fetch packets from the adapter. For the same reason, we send
-	packets without checking that the previous packet has been sent to
-	the LAN. We rely on the higher levels of the networking code to detect
-	missing packets and resend them.
-
-	Before we access the ATARI DMA controller, we check if another
-	process is using the DMA. If not, we lock the DMA, perform one or
-	more packet transfers and unlock the DMA before returning.
-	We do not use 'stdma_lock' unconditionally because it is unclear
-	if the networking code can be set to sleep, which will happen if
-	another (possibly slow) device is using the DMA controller.
-
-	The polling is done via timer interrupts which periodically
-	'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
-	between polls varies depending on an estimate of the net activity.
-	The allowed range is given by the variable 'bionet_min_poll_time'
-	for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
-	for the higher (slowest) limit.
-
-	Whenever a packet arrives, we switch to fastest response by setting
-	the polling time to its lowest limit. If the following poll fails,
-	because no packets have arrived, we increase the time for the next
-	poll. When the net activity is low, the polling time effectively
-	stays at its maximum value, resulting in the lowest load for the
-	machine.

- * Definitions of commands understood by the PAMs DMA adaptor.
- *
- * In general the DMA adaptor uses LUN 0, 5, 6 and 7 on one ID changeable
- * by the PAM's Net software.
- *
- * LUN 0 works as a harddisk. You can boot the PAM's Net driver there.
- * LUN 5 works as a harddisk and lets you access the RAM and some I/O HW
- *       area. In sector 0, bytes 0x38-0x3d you find the ethernet HW address
- *       of the adaptor.
- * LUN 6 works as a harddisk and lets you access the firmware ROM.
- * LUN 7 lets you send and receive packets.
- *
- * Some commands like the INQUIRY command work identical on all used LUNs.
- *
- * UNKNOWN1 seems to read some data.
- *          Command length is 6 bytes.
- * UNKNOWN2 seems to read some data (command byte 1 must be !=0). The
- *          following bytes seem to be something like an allocation length.
- *          Command length is 6 bytes.
- * READPKT  reads a packet received by the DMA adaptor.
- *          Command length is 6 bytes.
- * WRITEPKT sends a packet transferred by the following DMA phase. The length
- *          of the packet is transferred in command bytes 3 and 4.
- *          The adaptor automatically replaces the src hw address in an ethernet
- *          packet by its own hw address.
- *          Command length is 6 bytes.
- * INQUIRY  has the same function as the INQUIRY command supported by harddisks
- *          and other SCSI devices. It lets you detect which device you found
- *          at a given address.
- *          Command length is 6 bytes.
- * START    initializes the DMA adaptor. After this command it is able to send
- *          and receive packets. There is no status byte returned!
- *          Command length is 1 byte.
- * NUMPKTS  gives back the number of received packets waiting in the queue in
- *          the status byte.
- *          Command length is 1 byte.
- * UNKNOWN3
- * UNKNOWN4 Function of these three commands is unknown.
- * UNKNOWN5 The command length of these three commands is 1 byte.
- * DESELECT immediately deselects the DMA adaptor. May important with interrupt
- *          driven operation.
- *          Command length is 1 byte.
- * STOP     resets the DMA adaptor. After this command packets can no longer
- *          be received or transferred.
- *          Command length is 6 byte.

+/* 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.
