net-modules.txt
--- /dev/null
+IP Masquerading lets you run multiple machines on a network behind a
+Linux box so that all the machines (including the Linux masquerade box)
+appear as a single IP address to the outside world.
+
+The main use of masquerading is when your ISP only gives you one IP
+address and wants to charge like a wounded bull for multiple IP
+addresses. Instead of paying your ISP large amounts of money for a
+separate address for each of your machines, funnel them all through a
+Linux box running IP masquerading. Even when you have multiple IP
+addresses, you can still use masquerading if you want to hide your
+internal networks from the rest of the world.
+
+To activate IP masquerading, compile the kernel with IP Forwarding, IP
+Firewalling and IP Masquerading, the first two options must be on
+before you can see the masquerade option. Also consider using the
+ipautofw and ICMP masquerading suboptions.
+
+Some of the masq code is in the kernel, some is in modules so you have
+to make zImage and make modules. There are masq helper modules to
+handle special protocols, you only need to load a helper module if you
+want to use the corresponding protocol. Helper modules have to be
+explicitly loaded (usually from somewhere in /etc/rc.d), they cannot be
+loaded using kerneld. The current helper modules are ip_masq_ftp,
+ip_masq_irc, ip_masq_raudio, ip_masq_cuseeme, ip_masq_vdolive,
+ip_masq_quake.
+
+All of the modules can take a parameter specifying the port they work
+on - ie ftp handles connections to port 21 by default. This parameter,
+which can be ommitted to take the default port(s) makes the command
+line look like this
+ insmod ip_masq_raudio.o ports=7070,7071,7072
+Up to 12 ports can be specified (this value can be changed if you
+recompile).
+
+Masquerading is more of a server function than a single user function.
+Using it correctly requires some knowledge of TCP, UDP, IP and a high
+level understanding of some protocols. For more details on IP
+masquerading, visit
+ http://www.indyramp.com/masq/
+and read the HOWTO.
+
+There is a mailing list covering use of masqueraing, information can
+be found on the indyramp web site given above - please read the basic
+information before posting to the mailing list.

+/************************** DOCUMENTATION **************************/
+/*
+ * This driver provide a Linux interface to the Wavelan ISA hardware
+ * The Wavelan is a product of Lucent ("http://wavelan.netland.nl/").
+ * This division was formerly part of NCR and then AT&T.
+ * Wavelan are also distributed by DEC (RoamAbout), Digital Ocean and
+ * Aironet (Arlan). If you have one of those product, you will need to
+ * make some changes below...
+ *
+ * This driver is still a beta software. A lot of bugs have been corrected,
+ * a lot of functionalities are implemented, the whole appear pretty stable,
+ * but there is still some area of improvement (encryption, performance...).
+ *
+ * To know how to use this driver, read the NET3 HOWTO.
+ * If you want to exploit the many other fonctionalities, look comments
+ * in the code...
+ *
+ * This driver is the result of the effort of many peoples (see below).
+ */
+
+/* ------------------------ SPECIFIC NOTES ------------------------ */
+/*
+ * MAC address and hardware detection :
+ * ----------------------------------
+ * The detection code of the wavelan chech that the first 3
+ * octets of the MAC address fit the company code. This type of
+ * detection work well for AT&T cards (because the AT&T code is
+ * hardcoded in wavelan.h), but of course will fail for other
+ * manufacturer.
+ *
+ * If you are sure that your card is derived from the wavelan,
+ * here is the way to configure it :
+ * 1) Get your MAC address
+ * a) With your card utilities (wfreqsel, instconf, ...)
+ * b) With the driver :
+ * o compile the kernel with DEBUG_CONFIG_INFO enabled
+ * o Boot and look the card messages
+ * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
+ * 3) Compile & verify
+ * 4) Send me the MAC code - I will include it in the next version...
+ *
+ * "CU Inactive" message at boot up :
+ * -----------------------------------
+ * It seem that there is some weird timings problems with the
+ * Intel microcontroler. In fact, this message is triggered by a
+ * bad reading of the on board ram the first time we read the
+ * control block. If you ignore this message, all is ok (but in
+ * fact, currently, it reset the wavelan hardware).
+ *
+ * To get rid of that problem, there is two solution. The first
+ * is to add a dummy read of the scb at the end of
+ * wv_82586_config. The second is to add the timers
+ * wv_synchronous_cmd and wv_ack (the udelay just after the
+ * waiting loops - seem that the controler is not totally ready
+ * when it say it is !).
+ *
+ * In the current code, I use the second solution (to be
+ * consistent with the original solution of Bruce Janson).
+ */
+
+/* --------------------- WIRELESS EXTENSIONS --------------------- */
+/*
+ * This driver is the first one to support "wireless extensions".
+ * This set of extensions provide you some way to control the wireless
+ * caracteristics of the hardware in a standard way and support for
+ * applications for taking advantage of it (like Mobile IP).
+ *
+ * By default, these wireless extensions are disabled, because they
+ * need a patch to the Linux Kernel. This simple patch may be found
+ * with the driver + some utilities to access those wireless
+ * extensions (iwconfig...). Hopefully, those wireless extensions will
+ * make their way in the kernel someday.
+ *
+ * You also will need to enable the CONFIG_NET_RADIO in the kernel
+ * configuration to enable the wireless extensions.

+/*
+ * (Made with information in drivers headers. It may not be accurate,

+ *
+ * The history of the Wavelan drivers is as complicated as history of
+ * the Wavelan itself (NCR -> AT&T -> Lucent).
+ *
+ * All started with Anders Klemets <klemets@paul.rutgers.edu>,
+ * writting a Wavelan ISA driver for the MACH microkernel. Girish
+ * Welling <welling@paul.rutgers.edu> had also worked on it.
+ * Keith Moore modify this for the Pcmcia hardware.
+ *
+ * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
+ * and add specific Pcmcia support (there is currently no equivalent
+ * of the PCMCIA package under BSD...).
+ *
+ * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to freeBSD.
+ *
+ * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
+ *
+ * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
+ * (with help of the BSDI PCMCIA driver) for PCMCIA.
+ * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
+ * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
+ * correctly 2.00 cards (2.4 GHz with frequency selection).
+ * David Hinds <dhinds@hyper.stanford.edu> integrated the whole in his
+ * Pcmcia package (+ bug corrections).
+ *
+ * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
+ * patchs to the Pcmcia driver. After, I added code in the ISA driver
+ * for Wireless Extensions and full support of frequency selection
+ * cards. Then, I've done the same to the Pcmcia driver + some
+ * reorganisation. Finally, I came back to the ISA driver to
+ * upgrade it at the same level as the Pcmcia one and reorganise
+ * the code
+ * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
+ * much needed informations on the Wavelan hardware.

adapters which share a common programming interface across a diverse collection
of bus architectures by virtue of their MultiMaster ASIC technology. This
driver supports all present BusLogic MultiMaster Host Adapters, and should
-support any future MultiMaster designs with little or no modification. Host
-adapters based on the new FlashPoint architecture are not supported by this
-driver; consult the README.FlashPoint file for information about a program to
-upgrade Linux users from the unsupported FlashPoint LT to the supported BT-948.
+support any future MultiMaster designs with little or no modification. More
+recently, BusLogic has introduced the FlashPoint Host Adapters, which are less
+costly and rely on the host CPU, rather than including an onboard processor.
+Mylex/BusLogic has recently provided me with the FlashPoint Driver Developer's
+Kit, which comprises documentation and freely redistributable source code for
+the FlashPoint SCCB Manager. The SCCB Manager is the library of code that runs
+on the host CPU and performs functions analogous to the firmware on the
+MultiMaster Host Adapters. Thanks to their having provided the SCCB Manager,
+this driver now supports the FlashPoint Host Adapters as well.
My primary goals in writing this completely new BusLogic driver for Linux are
to achieve the full performance that BusLogic SCSI Host Adapters and modern
Linux kernel command line, allowing individual installations to tune driver
performance and error recovery to their particular needs.
-The most recent versions of this driver will always be available from my Linux
-Home Page at URL "http://www.dandelion.com/Linux/" and by anonymous FTP from
-ftp.dandelion.com. While only limited FTP directory listings are permitted,
-the introductory banner displayed on anonymous FTP login will provide a list of
-the driver versions and any other files that are available for retrieval.
+The latest information on Linux support for BusLogic SCSI Host Adapters, as
+well as the most recent release of this driver and the latest firmware for the
+BT-948/958/958D, will always be available from my Linux Home Page at URL
+"http://www.dandelion.com/Linux/".
Bug reports should be sent via electronic mail to "lnz@dandelion.com". Please
include with the bug report the complete configuration messages reported by the
o Robustness Features
The driver implements extensive error recovery procedures. When the higher
- level parts of the SCSI subsystem request that a command be reset, action is
- taken to restore proper operation of the host adapter and SCSI bus. On Linux
- 1.2.13, by default a full host adapter hard reset and SCSI bus reset is
- performed. On Linux 2.0.x, by default a selection is made between a full
- host adapter hard reset and SCSI bus reset versus sending a bus device reset
- message to the individual target device based on the recommendation of the
- SCSI subsystem. Error recovery strategies are selectable from the kernel
- command line individually for each target device, and also include sending a
- bus device reset to the specific target device associated with the command
- being reset, as well as suppressing error recovery entirely to avoid
- perturbing an improperly functioning device. If the bus device reset error
- recovery strategy is selected and sending a bus device reset does not restore
- correct operation, the next command that is reset will force a full host
- adapter hard reset and SCSI bus reset. SCSI bus resets caused by other
- devices and detected by the host adapter are also handled by issuing a hard
- reset to the host adapter and full re-initialization. Finally, if tagged
- queuing is active and more than one command reset occurs in a 10 minute
- interval, or if a command reset occurs within the first 10 minutes of
- operation, then tagged queuing will be disabled for that target device.
- These error recovery options should improve overall system robustness by
+ level parts of the SCSI subsystem request that a timed out command be reset,
+ a selection is made between a full host adapter hard reset and SCSI bus reset
+ versus sending a bus device reset message to the individual target device
+ based on the recommendation of the SCSI subsystem. Error recovery strategies

+ minutes of operation, then tagged queuing will be disabled for that target

preventing individual errant devices from causing the system as a whole to
lock up or crash, and thereby allowing a clean shutdown and restart after the
offending component is removed.
used to disable the ISA compatible I/O port entirely as it is not necessary.
The ISA compatible I/O port is disabled by default on the BT-948/958/958D.
+o /proc File System Support
+
+ Copies of the host adapter configuration information together with data
+ transfer and error recovery statistics are now available through the
+ /proc/scsi/BusLogic/<N> interface.
+
o Shared Interrupts Support
On systems that support shared interrupts, any number of BusLogic Host
- Adapters may share the same interrupt request channel, and in fact it is more
- efficient if they do so. The driver scans all known BusLogic Host Adapters
- whenever an interrupt is handled on an interrupt channel assigned to any
- BusLogic Host Adapter.

may be found in the comments before BusLogic_Setup in the kernel source code
file "BusLogic.c". The following examples may be useful as a starting point:
+ "BusLogic=NoProbe"
+
+ No probing of any kind is to be performed, and hence no BusLogic Host
+ Adapters will be detected.
+
+ "BusLogic=NoProbeISA"
+
+ No probing of the standard ISA I/O Addresses will be done, and hence only
+ PCI Host Adapters will be detected.
+
+ "BusLogic=NoProbePCI"
+
+ No interrogation of PCI Configuration Space will be made, and hence only
+ ISA Multimaster Host Adapters will be detected, as well as PCI Multimaster
+ Host Adapters that have their ISA Compatible I/O Port set to "Primary" or
+ "Alternate".
+
+ "BusLogic=NoSortPCI"
+
+ PCI MultiMaster Host Adapters will be enumerated in the order provided by
+ the PCI BIOS, ignoring any setting of the AutoSCSI "Use Bus And Device #
+ For PCI Scanning Seq." option.
+
+ "BusLogic=MultiMasterFirst"
+
+ By default, if both FlashPoint and PCI MultiMaster Host Adapters are
+ present, this driver will probe for FlashPoint Host Adapters first unless
+ the BIOS primary disk is controlled by the first PCI MultiMaster Host
+ Adapter, in which case MultiMaster Host Adapters will be probed first.
+ This option forces MultiMaster Host Adapters to be probed first.
+
+ "BusLogic=FlashPointFirst"
+
+ By default, if both FlashPoint and PCI MultiMaster Host Adapters are

which also disables tagged queuing. It may be useful if problems arise
during installation on a system with a flaky SCSI configuration. In cases
of a marginal SCSI configuration it may also be beneficial to disable fast

- series controllers. Disconnect/reconnect may also be disabled for fast
- devices such as disk drives, but should not be disabled for tape drives or
- other devices where a single command may take over a second to execute.

/*
* eata.c - Low-level driver for EATA/DMA SCSI host adapters.
*
+ * 24 Feb 1997 rev. 3.00 for linux 2.0.29 and 2.1.26
+ * When loading as a module, parameter passing is now supported
+ * both in 2.0 and in 2.1 style.
+ * Fixed data transfer direction for some SCSI opcodes.
+ * Immediate acknowledge to request sense commands.
+ * Linked commands to each disk device are now reordered by elevator
+ * sorting. Rare cases in which reordering of write requests could
+ * cause wrong results are managed.
+ * Fixed spurious timeouts caused by long simple queue tag sequences.
+ * New command line option (tm:[0-3]) to choose the type of tags:
+ * 0 -> mixed (default); 1 -> simple; 2 -> head; 3 -> ordered.
+ *
+ * 18 Jan 1997 rev. 2.60 for linux 2.1.21 and 2.0.28
+ * Added command line options to enable/disable linked commands
+ * (lc:[y|n]), tagged commands (tc:[y|n]) and to set the max queue
+ * depth (mq:xx). Default is "eata=lc:n,tc:n,mq:16".
+ * Improved command linking.
+ * Documented how to setup RAID-0 with DPT SmartRAID boards.
+ *
* 8 Jan 1997 rev. 2.50 for linux 2.1.20 and 2.0.27
* Added linked command support.
* Improved detection of PCI boards using ISA base addresses.
* When CONFIG_PCI is defined, BIOS32 is used to include in the
* list of i/o ports to be probed all the PCI SCSI controllers.
* The list of i/o ports to be probed can be overwritten by the
- * "eata=port0, port1,...." boot command line option.
+ * "eata=port0,port1,...." boot command line option.
* Scatter/gather lists are now allocated by a number of kmalloc
* calls, in order to avoid the previous size limit of 64Kb.
*
* v003.D0, firmware v07G.0).
*
* DPT SmartRAID boards support "Hardware Array" - a group of disk drives
- * which are all members of the same RAID-1 or RAID-5 array implemented
+ * which are all members of the same RAID-0, RAID-1 or RAID-5 array implemented
* in host adapter hardware. Hardware Arrays are fully compatible with this
* driver, since they look to it as a single disk drive.
- * By contrast RAID-0 are implemented as "Array Group", which does not
- * seem to be supported correctly by the actual SCSI subsystem.
- * To get RAID-0 functionality, the linux MD driver must be used instead of
- * the DPT "Array Group" feature.
+ *
+ * WARNING: to create a RAID-0 "Hardware Array" you must select "Other Unix"
+ * as the current OS in the DPTMGR "Initial System Installation" menu.
+ * Otherwise RAID-0 is generated as an "Array Group" (i.e. software RAID-0),
+ * which is not supported by the actual SCSI subsystem.
+ * To get the "Array Group" functionality, the Linux MD driver must be used
+ * instead of the DPT "Array Group" feature.
*
* Multiple ISA, EISA and PCI boards can be configured in the same system.
* It is suggested to put all the EISA boards on the same IRQ level, all
* - ISA 0x170, 0x230, 0x330.
*
* The above list of detection probes can be totally replaced by the
- * boot command line option: "eata=port0, port1, port2,...", where the
+ * boot command line option: "eata=port0,port1,port2,...", where the
* port0, port1... arguments are ISA/EISA/PCI addresses to be probed.
- * For example using "eata=0x7410, 0x7450, 0x230", the driver probes
+ * For example using "eata=0x7410,0x7450,0x230", the driver probes
* only the two PCI addresses 0x7410 and 0x7450 and the ISA address 0x230,
* in this order; "eata=0" totally disables this driver.
*
+ * After the optional list of detection probes, other possible command line
+ * options are:
+ *
+ * lc:y enables linked commands;
+ * lc:n disables linked commands;
+ * tc:y enables tagged commands;
+ * tc:n disables tagged commands;
+ * tm:0 use head/simple/ordered queue tag sequences for reads and ordered
+ * queue tags for writes;
+ * tm:1 use only simple queue tags;
+ * tm:2 use only head of queue tags;
+ * tm:3 use only ordered queue tags;
+ * mq:xx set the max queue depth to the value xx (2 <= xx <= 32).
+ *
+ * The default value is: "eata=lc:n,tc:n,mq:16,tm:0". An example using
+ * the list of detection probes could be: "eata=0x7410,0x230,lc:y,tc:n,mq:4".
+ *
+ * When loading as a module, parameters can be specified as well.
+ * The above example would be (use 1 in place of y and 0 in place of n):
+ *
+ * modprobe eata io_port=0x7410,0x230 linked_comm=1 tagged_comm=0 \
+ * max_queue_depth=4 tag_mode=0
+ *
+ * ----------------------------------------------------------------------------
+ * In this implementation, linked commands are designed to work with any DISK
+ * or CD-ROM, since this linking has only the intent of clustering (time-wise)
+ * and reordering by elevator sorting commands directed to each device,
+ * without any relation with the actual SCSI protocol between the controller
+ * and the device.
+ * If Q is the queue depth reported at boot time for each device (also named
+ * cmds/lun) and Q > 2, whenever there is already an active command to the
+ * device all other commands to the same device (up to Q-1) are kept waiting
+ * in the elevator sorting queue. When the active command completes, the
+ * commands in this queue are sorted by sector address. The sort is chosen
+ * between increasing or decreasing by minimizing the seek distance between
+ * the sector of the commands just completed and the sector of the first
+ * command in the list to be sorted.
+ * Trivial math assures that if there are (Q-1) outstanding request for
+ * random seeks over S sectors, the unsorted average seek distance is S/2,
+ * while the sorted average seek distance is S/(Q-1). The seek distance is
+ * hence divided by a factor (Q-1)/2.
+ * The above pure geometric remarks are valid in all cases and the
+ * driver effectively reduces the seek distance by the predicted factor
+ * when there are Q concurrent read i/o operations on the device, but this
+ * does not necessarily results in a noticeable performance improvement:
+ * your mileage may vary....
+ *
+ * Note: command reordering inside a batch of queued commands could cause
+ * wrong results only if there is at least one write request and the
+ * intersection (sector-wise) of all requests is not empty.
+ * When the driver detects a batch including overlapping requests
+ * (a really rare event) strict serial (pid) order is enforced.
+ * ----------------------------------------------------------------------------
+ *
* The boards are named EATA0, EATA1,... according to the detection order.
*
* In order to support multiple ISA boards in a reliable way,
* the driver sets host->wish_block = TRUE for all ISA boards.

* u14-34f.c - Low-level driver for UltraStor 14F/34F SCSI host adapters.
*
+ * 24 Feb 1997 rev. 3.00 for linux 2.0.29 and 2.1.26
+ * When loading as a module, parameter passing is now supported
+ * both in 2.0 and in 2.1 style.
+ * Fixed data transfer direction for some SCSI opcodes.
+ * Immediate acknowledge to request sense commands.
+ * Linked commands to each disk device are now reordered by elevator
+ * sorting. Rare cases in which reordering of write requests could
+ * cause wrong results are managed.
+ *
+ * 18 Jan 1997 rev. 2.60 for linux 2.1.21 and 2.0.28
+ * Added command line options to enable/disable linked commands
+ * (lc:[y|n]), old firmware support (of:[y|n]) and to set the max
+ * queue depth (mq:xx). Default is "u14-34f=lc:n,of:n,mq:8".
+ * Improved command linking.
+ *
* 8 Jan 1997 rev. 2.50 for linux 2.1.20 and 2.0.27
* Added linked command support.
*
*
* 22 Nov 1996 rev. 2.30 for linux 2.1.12 and 2.0.26
* The list of i/o ports to be probed can be overwritten by the
- * "u14-34f=port0, port1,...." boot command line option.
+ * "u14-34f=port0,port1,...." boot command line option.
* Scatter/gather lists are now allocated by a number of kmalloc
* calls, in order to avoid the previous size limit of 64Kb.
*
*
* Here a sample configuration using two U14F boards:
*
- U14F0: ISA 0x330, BIOS 0xc8000, IRQ 11, DMA 5, SG 32, MB 16, UC 1, LC 1, MQ 8.
- U14F1: ISA 0x340, BIOS 0x00000, IRQ 10, DMA 6, SG 32, MB 16, UC 1, LC 1, MQ 8.
+ U14F0: ISA 0x330, BIOS 0xc8000, IRQ 11, DMA 5, SG 32, MB 16, of:n, lc:y, mq:8.
+ U14F1: ISA 0x340, BIOS 0x00000, IRQ 10, DMA 6, SG 32, MB 16, of:n, lc:y, mq:8.
*
* The boot controller must have its BIOS enabled, while other boards can
* have their BIOS disabled, or enabled to an higher address.
* problems when using more then 16 scatter/gather lists.
*
* The list of i/o ports to be probed can be totally replaced by the
- * boot command line option: "u14-34f=port0, port1, port2,...", where the
+ * boot command line option: "u14-34f=port0,port1,port2,...", where the
* port0, port1... arguments are ISA/VESA addresses to be probed.
- * For example using "u14-34f=0x230, 0x340", the driver probes only the two
+ * For example using "u14-34f=0x230,0x340", the driver probes only the two
* addresses 0x230 and 0x340 in this order; "u14-34f=0" totally disables
* this driver.
*
+ * After the optional list of detection probes, other possible command line
+ * options are:
+ *
+ * lc:y enables linked commands;
+ * lc:n disables linked commands;
+ * of:y enables old firmware support;
+ * of:n disables old firmware support;
+ * mq:xx set the max queue depth to the value xx (2 <= xx <= 8).
+ *
+ * The default value is: "u14-34f=lc:n,of:n,mq:8". An example using the list
+ * of detection probes could be: "u14-34f=0x230,0x340,lc:y,of:n,mq:4".
+ *
+ * When loading as a module, parameters can be specified as well.
+ * The above example would be (use 1 in place of y and 0 in place of n):
+ *
+ * modprobe u14-34f io_port=0x230,0x340 linked_comm=1 have_old_firmware=0 \
+ * max_queue_depth=4
+ *
+ * ----------------------------------------------------------------------------
+ * In this implementation, linked commands are designed to work with any DISK
+ * or CD-ROM, since this linking has only the intent of clustering (time-wise)
+ * and reordering by elevator sorting commands directed to each device,
+ * without any relation with the actual SCSI protocol between the controller
+ * and the device.
+ * If Q is the queue depth reported at boot time for each device (also named
+ * cmds/lun) and Q > 2, whenever there is already an active command to the
+ * device all other commands to the same device (up to Q-1) are kept waiting
+ * in the elevator sorting queue. When the active command completes, the
+ * commands in this queue are sorted by sector address. The sort is chosen
+ * between increasing or decreasing by minimizing the seek distance between
+ * the sector of the commands just completed and the sector of the first
+ * command in the list to be sorted.
+ * Trivial math assures that if there are (Q-1) outstanding request for
+ * random seeks over S sectors, the unsorted average seek distance is S/2,
+ * while the sorted average seek distance is S/(Q-1). The seek distance is
+ * hence divided by a factor (Q-1)/2.
+ * The above pure geometric remarks are valid in all cases and the
+ * driver effectively reduces the seek distance by the predicted factor
+ * when there are Q concurrent read i/o operations on the device, but this
+ * does not necessarily results in a noticeable performance improvement:
+ * your mileage may vary....
+ *
+ * Note: command reordering inside a batch of queued commands could cause
+ * wrong results only if there is at least one write request and the
+ * intersection (sector-wise) of all requests is not empty.
+ * When the driver detects a batch including overlapping requests
+ * (a really rare event) strict serial (pid) order is enforced.
+ * ----------------------------------------------------------------------------
+ *
* The boards are named Ux4F0, Ux4F1,... according to the detection order.
*
* In order to support multiple ISA boards in a reliable way,
* the driver sets host->wish_block = TRUE for all ISA boards.

+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands. This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ * net/core/dev.c (two place + add include)
+ * net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ * net/core/dev.c (two other places)
+ * include/linux/netdevice.h (one place)
+ * include/linux/proc_fs.h (one place)
+ *
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...

*
* Author: Nigel Metheringham
* [strongly based on ftp module by Juan Jose Ciarlante & Wouter Gadeyne]
* [Real Audio information taken from Progressive Networks firewall docs]
- *
+ * [Kudos to Progressive Networks for making the protocol specs available]
*
*
*
* When the link is up there appears to be enough control data
* crossing the control link to keep it open even if a long audio
* piece is playing.
+ *
+ * The Robust UDP support added in RealAudio 3.0 is supported, but due
+ * to servers/clients not making great use of this has not been greatly
+ * tested. RealVideo (as used in the Real client version 4.0beta1) is
+ * supported but again is not greatly tested (bandwidth requirements
+ * appear to exceed that available at the sites supporting the protocol).
+ *
+ * Multiple Port Support
+ * The helper can be made to handle up to MAX_MASQ_APP_PORTS (normally 12)
+ * with the port numbers being defined at module load time. The module
+ * uses the symbol "ports" to define a list of monitored ports, which can
+ * be specified on the insmod command line as
+ * ports=x1,x2,x3...
+ * where x[n] are integer port numbers. This option can be put into
+ * /etc/conf.modules (or /etc/modules.conf depending on your config)
+ * where modload will pick it up should you use modload to load your
+ * modules.
