33 Say Y if you have a Metricom radio and intend to use Starmode Radio
34 IP. STRIP is a radio protocol developed for the MosquitoNet project
35 to send Internet traffic using Metricom radios. Metricom radios are
36 small, battery powered, 100kbit/sec packet radio transceivers, about
37 the size and weight of a cellular telephone. (You may also have heard
38 them called "Metricom modems" but we avoid the term "modem" because
39 it misleads many people into thinking that you can plug a Metricom
40 modem into a phone line and use it as a modem.)
41
42 You can use STRIP on any Linux machine with a serial port, although
43 it is obviously most useful for people with laptop computers. If you
44 think you might get a Metricom radio in the future, there is no harm
45 in saying Y to STRIP now, except that it makes the kernel a bit
46 bigger.

56 Aironet makes Arlan, a class of wireless LAN adapters. These use the

58 This driver is tested on the 655 and IC2200 series cards. Look at
59 <http://www.ylenurme.ee/~elmer/655/> for the latest information.
60
61 The driver is built as two modules, arlan and arlan-proc. The latter
62 is the /proc interface and is not needed most of time.

2 *
3 * Filename: netwave_cs.c
4 * Version: 0.4.1
5 * Description: Netwave AirSurfer Wireless LAN PC Card driver
6 * Status: Experimental.
7 * Authors: John Markus Bjørndalen <johnm@cs.uit.no>
8 * Dag Brattli <dagb@cs.uit.no>
9 * David Hinds <dahinds@users.sourceforge.net>
10 * Created at: A long time ago!
11 * Modified at: Mon Nov 10 11:54:37 1997
12 * Modified by: Dag Brattli <dagb@cs.uit.no>
13 *
14 * Copyright (c) 1997 University of Tromsø, Norway
15 *
16 * Revision History:
17 *
18 * 08-Nov-97 15:14:47 John Markus Bjørndalen <johnm@cs.uit.no>
19 * - Fixed some bugs in netwave_rx and cleaned it up a bit.
20 * (One of the bugs would have destroyed packets when receiving
21 * multiple packets per interrupt).
22 * - Cleaned up parts of newave_hw_xmit.
23 * - A few general cleanups.
24 * 24-Oct-97 13:17:36 Dag Brattli <dagb@cs.uit.no>
25 * - Fixed netwave_rx receive function (got updated docs)
26 * Others:
27 * - Changed name from xircnw to netwave, take a look at
28 * http://www.netwave-wireless.com
29 * - Some reorganizing of the code
30 * - Removed possible race condition between interrupt handler and transmit
31 * function
32 * - Started to add wireless extensions, but still needs some coding
33 * - Added watchdog for better handling of transmission timeouts
34 * (hopefully this works better)

220 A struct pcmcia_device structure has fields for most things that are needed

222 specific information that also needs to be kept track of. The
223 'priv' pointer in a struct pcmcia_device structure can be used to point to
224 a device-specific private data structure, like this.
225
226 A driver needs to provide a dev_node_t structure for each device
227 on a card. In some cases, there is only one device per card (for
228 example, ethernet cards, modems). In other cases, there may be
229 many actual or logical devices (SCSI adapters, memory cards with
230 multiple partitions). The dev_node_t structures need to be kept
231 in a linked list starting at the 'dev' field of a struct pcmcia_device
232 structure. We allocate them in the card's private data structure,
233 because they generally can't be allocated dynamically.

16 *
17 * Version: @(#)strip.c 1.3 July 1997
18 *
19 * Author: Stuart Cheshire <cheshire@cs.stanford.edu>
20 *
21 * Fixes: v0.9 12th Feb 1996 (SC)
22 * New byte stuffing (2+6 run-length encoding)
23 * New watchdog timer task
24 * New Protocol key (SIP0)
25 *
26 * v0.9.1 3rd March 1996 (SC)
27 * Changed to dynamic device allocation -- no more compile
28 * time (or boot time) limit on the number of STRIP devices.
29 *
30 * v0.9.2 13th March 1996 (SC)
31 * Uses arp cache lookups (but doesn't send arp packets yet)
32 *
33 * v0.9.3 17th April 1996 (SC)
34 * Fixed bug where STR_ERROR flag was getting set unneccessarily
35 * (causing otherwise good packets to be unneccessarily dropped)
36 *
37 * v0.9.4 27th April 1996 (SC)
38 * First attempt at using "&COMMAND" Starmode AT commands
39 *
40 * v0.9.5 29th May 1996 (SC)
41 * First attempt at sending (unicast) ARP packets
42 *
43 * v0.9.6 5th June 1996 (Elliot)
44 * Put "message level" tags in every "printk" statement
45 *
46 * v0.9.7 13th June 1996 (laik)
47 * Added support for the /proc fs
48 *
49 * v0.9.8 July 1996 (Mema)
50 * Added packet logging
51 *
52 * v1.0 November 1996 (SC)
53 * Fixed (severe) memory leaks in the /proc fs code
54 * Fixed race conditions in the logging code
55 *
56 * v1.1 January 1997 (SC)
57 * Deleted packet logging (use tcpdump instead)
58 * Added support for Metricom Firmware v204 features
59 * (like message checksums)
60 *
61 * v1.2 January 1997 (SC)
62 * Put portables list back in
63 *
64 * v1.3 July 1997 (SC)
65 * Made STRIP driver set the radio's baud rate automatically.
66 * It is no longer necessarily to manually set the radio's
67 * rate permanently to 115200 -- the driver handles setting
68 * the rate automatically.

301 * Note: manual_dev_addr hack
302 *
303 * It is not possible to change the hardware address of a Metricom radio,
304 * or to send packets with a user-specified hardware source address, thus
305 * trying to manually set a hardware source address is a questionable
306 * thing to do. However, if the user *does* manually set the hardware
307 * source address of a STRIP interface, then the kernel will believe it,
308 * and use it in certain places. For example, the hardware address listed
309 * by ifconfig will be the manual address, not the true one.
310 * (Both addresses are listed in /proc/net/strip.)
311 * Also, ARP packets will be sent out giving the user-specified address as
312 * the source address, not the real address. This is dangerous, because
313 * it means you won't receive any replies -- the ARP replies will go to
314 * the specified address, which will be some other radio. The case where
315 * this is useful is when that other radio is also connected to the same
316 * machine. This allows you to connect a pair of radios to one machine,
317 * and to use one exclusively for inbound traffic, and the other
318 * exclusively for outbound traffic. Pretty neat, huh?
319 *
320 * Here's the full procedure to set this up:
321 *
322 * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
323 * and st1 for incoming packets
324 *
325 * 2. "ifconfig" st0 (outbound radio) to have the hardware address
326 * which is the real hardware address of st1 (inbound radio).
327 * Now when it sends out packets, it will masquerade as st1, and
328 * replies will be sent to that radio, which is exactly what we want.
329 *
330 * 3. Set the route table entry ("route add default ..." or
331 * "route add -net ...", as appropriate) to send packets via the st0
332 * interface (outbound radio). Do not add any route which sends packets
333 * out via the st1 interface -- that radio is for inbound traffic only.
334 *
335 * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
336 * This tells the STRIP driver to "shut down" that interface and not
337 * send any packets through it. In particular, it stops sending the
338 * periodic gratuitous ARP packets that a STRIP interface normally sends.
339 * Also, when packets arrive on that interface, it will search the
340 * interface list to see if there is another interface who's manual
341 * hardware address matches its own real address (i.e. st0 in this
342 * example) and if so it will transfer ownership of the skbuff to
343 * that interface, so that it looks to the kernel as if the packet
344 * arrived on that interface. This is necessary because when the
345 * kernel sends an ARP packet on st0, it expects to get a reply on
346 * st0, and if it sees the reply come from st1 then it will ignore
347 * it (to be accurate, it puts the entry in the ARP table, but
348 * labelled in such a way that st0 can't use it).
349 *
350 * Thanks to Petros Maniatis for coming up with the idea of splitting
351 * inbound and outbound traffic between two interfaces, which turned
352 * out to be really easy to implement, even if it is a bit of a hack.
353 *
354 * Having set a manual address on an interface, you can restore it
355 * to automatic operation (where the address is automatically kept
356 * consistent with the real address of the radio) by setting a manual
357 * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
358 * This 'turns off' manual override mode for the device address.
359 *
360 * Note: The IEEE 802 headers reported in tcpdump will show the *real*
361 * radio addresses the packets were sent and received from, so that you
362 * can see what is really going on with packets, and which interfaces
363 * they are really going through.

9 * This file contains the declarations for the WaveLAN hardware. Note that
10 * the WaveLAN ISA includes a i82586 controller (see definitions in
11 * file i82586.h).
12 *
13 * The main difference between the ISA hardware and the PCMCIA one is
14 * the Ethernet controller (i82586 instead of i82593).
15 * The i82586 allows multiple transmit buffers. The PSA needs to be accessed
16 * through the host interface.

17/*
18 * This driver provides a Linux interface to the WaveLAN ISA hardware.
19 * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
20 * This division was formerly part of NCR and then AT&T.
21 * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
22 *
23 * To learn how to use this driver, read the NET3 HOWTO.
24 * If you want to exploit the many other functionalities, read the comments
25 * in the code.
26 *
27 * This driver is the result of the effort of many people (see below).

30/* ------------------------ SPECIFIC NOTES ------------------------ */
31/*
32 * Web page
33 * --------
34 * I try to maintain a web page with the Wireless LAN Howto at :
35 * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
36 *
37 * SMP
38 * ---
39 * We now are SMP compliant (I eventually fixed the remaining bugs).
40 * The driver has been tested on a dual P6-150 and survived my usual
41 * set of torture tests.
42 * Anyway, I spent enough time chasing interrupt re-entrancy during
43 * errors or reconfigure, and I designed the locked/unlocked sections
44 * of the driver with great care, and with the recent addition of
45 * the spinlock (thanks to the new API), we should be quite close to
46 * the truth.
47 * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
48 * but better safe than sorry (especially at 2 Mb/s ;-).
49 *
50 * I have also looked into disabling only our interrupt on the card
51 * (via HACR) instead of all interrupts in the processor (via cli),
52 * so that other driver are not impacted, and it look like it's
53 * possible, but it's very tricky to do right (full of races). As
54 * the gain would be mostly for SMP systems, it can wait...
55 *
56 * Debugging and options
57 * ---------------------
58 * You will find below a set of '#define" allowing a very fine control
59 * on the driver behaviour and the debug messages printed.
60 * The main options are :
61 * o SET_PSA_CRC, to have your card correctly recognised by
62 * an access point and the Point-to-Point diagnostic tool.
63 * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
64 * (otherwise we always start afresh with some defaults)
65 *
66 * wavelan.o is too darned big
67 * ---------------------------
68 * That's true! There is a very simple way to reduce the driver
69 * object by 33%! Comment out the following line:
70 * #include <linux/wireless.h>
71 * Other compile options can also reduce the size of it...
72 *
73 * MAC address and hardware detection:
74 * -----------------------------------
75 * The detection code for the WaveLAN checks that the first three
76 * octets of the MAC address fit the company code. This type of
77 * detection works well for AT&T cards (because the AT&T code is
78 * hardcoded in wavelan.h), but of course will fail for other
79 * manufacturers.
80 *
81 * If you are sure that your card is derived from the WaveLAN,
82 * here is the way to configure it:
83 * 1) Get your MAC address
84 * a) With your card utilities (wfreqsel, instconf, etc.)
85 * b) With the driver:
86 * o compile the kernel with DEBUG_CONFIG_INFO enabled
87 * o Boot and look the card messages
88 * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
89 * 3) Compile and verify
90 * 4) Send me the MAC code. I will include it in the next version.
91 *
92 */
93
94/* --------------------- WIRELESS EXTENSIONS --------------------- */
95/*
96 * This driver is the first to support "wireless extensions".
97 * This set of extensions provides a standard way to control the wireless
98 * characteristics of the hardware. Applications such as mobile IP may
99 * take advantage of it.
100 *
101 * It might be a good idea as well to fetch the wireless tools to
102 * configure the device and play a bit.

116/* --------------------------- HISTORY --------------------------- */
117/*
118 * This is based on information in the drivers' headers. It may not be
119 * accurate, and I guarantee only my best effort.
120 *
121 * The history of the WaveLAN drivers is as complicated as the history of
122 * the WaveLAN itself (NCR -> AT&T -> Lucent).
123 *
124 * It all started with Anders Klemets <klemets@paul.rutgers.edu>
125 * writing a WaveLAN ISA driver for the Mach microkernel. Girish
126 * Welling <welling@paul.rutgers.edu> had also worked on it.
127 * Keith Moore modified this for the PCMCIA hardware.
128 *
129 * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
130 * and added specific PCMCIA support (there is currently no equivalent
131 * of the PCMCIA package under BSD).
132 *
133 * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
134 *
135 * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
136 *
137 * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
138 * (with help of the BSDI PCMCIA driver) for PCMCIA.
139 * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
140 * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
141 * 2.00 cards correctly (2.4 GHz with frequency selection).
142 * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
143 * PCMCIA package (and bug corrections).
144 *
145 * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
146 * patches to the PCMCIA driver. Later, I added code in the ISA driver
147 * for Wireless Extensions and full support of frequency selection
148 * cards. Then, I did the same to the PCMCIA driver, and did some
149 * reorganisation. Finally, I came back to the ISA driver to
150 * upgrade it at the same level as the PCMCIA one and reorganise
151 * the code.
152 * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
153 * much needed information on the WaveLAN hardware.

14 * the Ethernet Controller (i82593 instead of i82586). The i82593 allow
15 * only one send buffer. The PSA (Parameter Storage Area : EEprom for
16 * permanent storage of various info) is memory mapped, but not the
17 * MMI (Modem Management Interface).

17/*
18 * This driver provide a Linux interface to the Wavelan Pcmcia hardware
19 * The Wavelan is a product of Lucent (http://www.wavelan.com/).
20 * This division was formerly part of NCR and then AT&T.
21 * Wavelan are also distributed by DEC (RoamAbout DS)...
22 *
23 * To know how to use this driver, read the PCMCIA HOWTO.
24 * If you want to exploit the many other fonctionalities, look comments
25 * in the code...
26 *
27 * This driver is the result of the effort of many peoples (see below).
28 */
29
30/* ------------------------ SPECIFIC NOTES ------------------------ */
31/*
32 * Web page
33 * --------
34 * I try to maintain a web page with the Wireless LAN Howto at :
35 * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
36 *
37 * SMP
38 * ---
39 * We now are SMP compliant (I eventually fixed the remaining bugs).
40 * The driver has been tested on a dual P6-150 and survived my usual
41 * set of torture tests.
42 * Anyway, I spent enough time chasing interrupt re-entrancy during
43 * errors or reconfigure, and I designed the locked/unlocked sections
44 * of the driver with great care, and with the recent addition of
45 * the spinlock (thanks to the new API), we should be quite close to
46 * the truth.
47 * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
48 * but better safe than sorry (especially at 2 Mb/s ;-).
49 *
50 * I have also looked into disabling only our interrupt on the card
51 * (via HACR) instead of all interrupts in the processor (via cli),
52 * so that other driver are not impacted, and it look like it's
53 * possible, but it's very tricky to do right (full of races). As
54 * the gain would be mostly for SMP systems, it can wait...
55 *
56 * Debugging and options
57 * ---------------------
58 * You will find below a set of '#define" allowing a very fine control
59 * on the driver behaviour and the debug messages printed.
60 * The main options are :
61 * o WAVELAN_ROAMING, for the experimental roaming support.
62 * o SET_PSA_CRC, to have your card correctly recognised by
63 * an access point and the Point-to-Point diagnostic tool.
64 * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
65 * (otherwise we always start afresh with some defaults)
66 *
67 * wavelan_cs.o is darn too big
68 * -------------------------
69 * That's true ! There is a very simple way to reduce the driver
70 * object by 33% (yes !). Comment out the following line :
71 * #include <linux/wireless.h>
72 * Other compile options can also reduce the size of it...
73 *
74 * MAC address and hardware detection :
75 * ----------------------------------
76 * The detection code of the wavelan chech that the first 3
77 * octets of the MAC address fit the company code. This type of
78 * detection work well for AT&T cards (because the AT&T code is
79 * hardcoded in wavelan_cs.h), but of course will fail for other
80 * manufacturer.
81 *
82 * If you are sure that your card is derived from the wavelan,
83 * here is the way to configure it :
84 * 1) Get your MAC address
85 * a) With your card utilities (wfreqsel, instconf, ...)
86 * b) With the driver :
87 * o compile the kernel with DEBUG_CONFIG_INFO enabled
88 * o Boot and look the card messages
89 * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
90 * 3) Compile & verify
91 * 4) Send me the MAC code - I will include it in the next version...
92 *
93 */
94
95/* --------------------- WIRELESS EXTENSIONS --------------------- */
96/*
97 * This driver is the first one to support "wireless extensions".
98 * This set of extensions provide you some way to control the wireless
99 * caracteristics of the hardware in a standard way and support for
100 * applications for taking advantage of it (like Mobile IP).
101 *
102 * It might be a good idea as well to fetch the wireless tools to
103 * configure the device and play a bit.

117/* --------------------------- HISTORY --------------------------- */
118/*
119 * The history of the Wavelan drivers is as complicated as history of
120 * the Wavelan itself (NCR -> AT&T -> Lucent).
121 *
122 * All started with Anders Klemets <klemets@paul.rutgers.edu>,
123 * writing a Wavelan ISA driver for the MACH microkernel. Girish
124 * Welling <welling@paul.rutgers.edu> had also worked on it.
125 * Keith Moore modify this for the Pcmcia hardware.
126 *
127 * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
128 * and add specific Pcmcia support (there is currently no equivalent
129 * of the PCMCIA package under BSD...).
130 *
131 * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
132 *
133 * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
134 *
135 * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
136 * (with help of the BSDI PCMCIA driver) for PCMCIA.
137 * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
138 * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
139 * correctly 2.00 cards (2.4 GHz with frequency selection).
140 * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
141 * Pcmcia package (+ bug corrections).
142 *
143 * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
144 * patchs to the Pcmcia driver. After, I added code in the ISA driver
145 * for Wireless Extensions and full support of frequency selection
146 * cards. Now, I'm doing the same to the Pcmcia driver + some
147 * reorganisation.
148 * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
149 * much needed informations on the Wavelan hardware.

153 * Almost everybody wrote code under GNU or BSD license (or alike),
154 * and want that their original copyright remain somewhere in the

156 * Nobody want to take responsibility for anything, except the fame...
