Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

8 AppleTalk is the protocol that Apple computers can use to communicate
9 on a network. If your Linux box is connected to such a network, and wish
10 to do IP over it, or you have a LocalTalk card and wish to use it to
11 connect to the AppleTalk network, say Y.

16 depends on DEV_APPLETALK && (ISA || EISA)
17 help
18 This allows you to use the AppleTalk PC card to connect to LocalTalk
19 networks. The card is also known as the Farallon PhoneNet PC card.
20 If you are in doubt, this card is the one with the 65C02 chip on it.
21 You also need version 1.3.3 or later of the netatalk package.
22 This driver is experimental, which means that it may not work.
23 See the file <file:Documentation/networking/ltpc.txt>.
24

28 help
29 This allows you to use COPS AppleTalk cards to connect to LocalTalk
30 networks. You also need version 1.3.3 or later of the netatalk
31 package. This driver is experimental, which means that it may not
32 work. This driver will only work if you choose "AppleTalk DDP"
33 networking support, above.
34 Please read the file <file:Documentation/networking/cops.txt>.

51config IPDDP
52 tristate "Appletalk-IP driver support"
53 depends on DEV_APPLETALK && ATALK
54 ---help---
55 This allows IP networking for users who only have AppleTalk
56 networking available. This feature is experimental. With this
57 driver, you can encapsulate IP inside AppleTalk (e.g. if your Linux
58 box is stuck on an AppleTalk only network) or decapsulate (e.g. if
59 you want your Linux box to act as an Internet gateway for a zoo of
60 AppleTalk connected Macs). Please see the file
61 <file:Documentation/networking/ipddp.txt> for more information.
62
63 If you say Y here, the AppleTalk-IP support will be compiled into
64 the kernel. In this case, you can either use encapsulation or
65 decapsulation, but not both. With the following two questions, you
66 decide which one you want.
67
68 To compile the AppleTalk-IP support as a module, choose M here: the
69 module will be called ipddp.
70 In this case, you will be able to use both encapsulation and
71 decapsulation simultaneously, by loading two copies of the module
72 and specifying different values for the module option ipddp_mode.
73
74config IPDDP_ENCAP
75 bool "IP to Appletalk-IP Encapsulation support"
76 depends on IPDDP
77 help
78 If you say Y here, the AppleTalk-IP code will be able to encapsulate
79 IP packets inside AppleTalk frames; this is useful if your Linux box
80 is stuck on an AppleTalk network (which hopefully contains a
81 decapsulator somewhere). Please see
82 <file:Documentation/networking/ipddp.txt> for more information. If
83 you said Y to "AppleTalk-IP driver support" above and you say Y
84 here, then you cannot say Y to "AppleTalk-IP to IP Decapsulation
85 support", below.
86
87config IPDDP_DECAP

89 depends on IPDDP
90 help
91 If you say Y here, the AppleTalk-IP code will be able to decapsulate
92 AppleTalk-IP frames to IP packets; this is useful if you want your
93 Linux box to act as an Internet gateway for an AppleTalk network.
94 Please see <file:Documentation/networking/ipddp.txt> for more
95 information. If you said Y to "AppleTalk-IP driver support" above
96 and you say Y here, then you cannot say Y to "IP to AppleTalk-IP
97 Encapsulation support", above.

105 * this driver.
106 *
107 * This driver has 2 modes and they are: Dayna mode and Tangent mode.
108 * Each mode corresponds with the type of card. It has been found
109 * that there are 2 main types of cards and all other cards are
110 * the same and just have different names or only have minor differences
111 * such as more IO ports. As this driver is tested it will
112 * become more clear on exactly what cards are supported. The driver
113 * defaults to using Dayna mode. To change the drivers mode, simply
114 * select Dayna or Tangent mode when configuring the kernel.
115 *
116 * This driver should support:
117 * TANGENT driver mode:
118 * Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200,
119 * COPS LT-1
120 * DAYNA driver mode:
121 * Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95,
122 * Farallon PhoneNET PC III, Farallon PhoneNET PC II
123 * Other cards possibly supported mode unkown though:
124 * Dayna DL2000 (Full length), COPS LT/M (Micro-Channel)
125 *
126 * Cards NOT supported by this driver but supported by the ltpc.c
127 * driver written by Bradford W. Johnson <johns393@maroon.tc.umn.edu>
128 * Farallon PhoneNET PC
129 * Original Apple LocalTalk PC card
130 *
131 * N.B.
132 *
133 * The Daystar Digital LT200 boards do not support interrupt-driven
134 * IO. You must specify 'irq=0xff' as a module parameter to invoke
135 * polled mode. I also believe that the port probing logic is quite
136 * dangerous at best and certainly hopeless for a polled card. Best to
137 * specify both. - Steve H.

1/*** ltpc.c -- a driver for the LocalTalk PC card.
2 *
3 * Copyright (c) 1995,1996 Bradford W. Johnson <johns393@maroon.tc.umn.edu>
4 *
5 * This software may be used and distributed according to the terms
6 * of the GNU General Public License, incorporated herein by reference.
7 *
8 * This is ALPHA code at best. It may not work for you. It may
9 * damage your equipment. It may damage your relations with other
10 * users of your network. Use it at your own risk!
11 *
12 * Based in part on:
13 * skeleton.c by Donald Becker
14 * dummy.c by Nick Holloway and Alan Cox
15 * loopback.c by Ross Biro, Fred van Kampen, Donald Becker
16 * the netatalk source code (UMICH)
17 * lots of work on the card...
18 *
19 * I do not have access to the (proprietary) SDK that goes with the card.
20 * If you do, I don't want to know about it, and you can probably write
21 * a better driver yourself anyway. This does mean that the pieces that
22 * talk to the card are guesswork on my part, so use at your own risk!
23 *
24 * This is my first try at writing Linux networking code, and is also
25 * guesswork. Again, use at your own risk! (Although on this part, I'd
26 * welcome suggestions)
27 *
28 * This is a loadable kernel module which seems to work at my site
29 * consisting of a 1.2.13 linux box running netatalk 1.3.3, and with
30 * the kernel support from 1.3.3b2 including patches routing.patch
31 * and ddp.disappears.from.chooser. In order to run it, you will need
32 * to patch ddp.c and aarp.c in the kernel, but only a little...
33 *
34 * I'm fairly confident that while this is arguably badly written, the
35 * problems that people experience will be "higher level", that is, with
36 * complications in the netatalk code. The driver itself doesn't do
37 * anything terribly complicated -- it pretends to be an ether device
38 * as far as netatalk is concerned, strips the DDP data out of the ether
39 * frame and builds a LLAP packet to send out the card. In the other
40 * direction, it receives LLAP frames from the card and builds a fake
41 * ether packet that it then tosses up to the networking code. You can
42 * argue (correctly) that this is an ugly way to do things, but it
43 * requires a minimal amount of fooling with the code in ddp.c and aarp.c.
44 *
45 * The card will do a lot more than is used here -- I *think* it has the
46 * layers up through ATP. Even if you knew how that part works (which I
47 * don't) it would be a big job to carve up the kernel ddp code to insert
48 * things at a higher level, and probably a bad idea...
49 *
50 * There are a number of other cards that do LocalTalk on the PC. If
51 * nobody finds any insurmountable (at the netatalk level) problems
52 * here, this driver should encourage people to put some work into the
53 * other cards (some of which I gather are still commercially available)
54 * and also to put hooks for LocalTalk into the official ddp code.
55 *
56 * I welcome comments and suggestions. This is my first try at Linux
57 * networking stuff, and there are probably lots of things that I did
58 * suboptimally.

65 * Revision 1.1.2.1 2000/03/01 05:35:07 jgarzik
66 * at and tr cleanup
67 *
68 * Revision 1.8 1997/01/28 05:44:54 bradford
69 * Clean up for non-module a little.
70 * Hacked about a bit to clean things up - Alan Cox
71 * Probably broken it from the origina 1.8
72 *
73
74 * 1998/11/09: David Huggins-Daines <dhd@debian.org>
75 * Cleaned up the initialization code to use the standard autoirq methods,
76 and to probe for things in the standard order of i/o, irq, dma. This
77 removes the "reset the reset" hack, because I couldn't figure out an
78 easy way to get the card to trigger an interrupt after it.
79 * Added support for passing configuration parameters on the kernel command
80 line and through insmod
81 * Changed the device name from "ltalk0" to "lt0", both to conform with the
82 other localtalk driver, and to clear up the inconsistency between the
83 module and the non-module versions of the driver :-)
84 * Added a bunch of comments (I was going to make some enums for the state
85 codes and the register offsets, but I'm still not sure exactly what their
86 semantics are)
87 * Don't poll anymore in interrupt-driven mode
88 * It seems to work as a module now (as of 2.1.127), but I don't think
89 I'm responsible for that...
90
91 *
92 * Revision 1.7 1996/12/12 03:42:33 bradford
93 * DMA alloc cribbed from 3c505.c.
94 *
95 * Revision 1.6 1996/12/12 03:18:58 bradford
96 * Added virt_to_bus; works in 2.1.13.
97 *
98 * Revision 1.5 1996/12/12 03:13:22 root
99 * xmitQel initialization -- think through better though.
100 *
101 * Revision 1.4 1996/06/18 14:55:55 root
102 * Change names to ltpc. Tabs. Took a shot at dma alloc,
103 * although more needs to be done eventually.
104 *
105 * Revision 1.3 1996/05/22 14:59:39 root
106 * Change dev->open, dev->close to track dummy.c in 1.99.(around 7)
107 *
108 * Revision 1.2 1996/05/22 14:58:24 root
109 * Change tabs mostly.
110 *
111 * Revision 1.1 1996/04/23 04:45:09 root
112 * Initial revision
113 *
114 * Revision 0.16 1996/03/05 15:59:56 root
115 * Change ARPHRD_LOCALTLK definition to the "real" one.
116 *
117 * Revision 0.15 1996/03/05 06:28:30 root
118 * Changes for kernel 1.3.70. Still need a few patches to kernel, but
119 * it's getting closer.
120 *
121 * Revision 0.14 1996/02/25 17:38:32 root
122 * More cleanups. Removed query to card on get_stats.
123 *
124 * Revision 0.13 1996/02/21 16:27:40 root
125 * Refix debug_print_skb. Fix mac.raw gotcha that appeared in 1.3.65.
126 * Clean up receive code a little.
127 *
128 * Revision 0.12 1996/02/19 16:34:53 root
129 * Fix debug_print_skb. Kludge outgoing snet to 0 when using startup
130 * range. Change debug to mask: 1 for verbose, 2 for higher level stuff
131 * including packet printing, 4 for lower level (card i/o) stuff.
132 *
133 * Revision 0.11 1996/02/12 15:53:38 root
134 * Added router sends (requires new aarp.c patch)
135 *
136 * Revision 0.10 1996/02/11 00:19:35 root
137 * Change source LTALK_LOGGING debug switch to insmod ... debug=2.
138 *
139 * Revision 0.9 1996/02/10 23:59:35 root
140 * Fixed those fixes for 1.2 -- DANGER! The at.h that comes with netatalk
141 * has a *different* definition of struct sockaddr_at than the Linux kernel
142 * does. This is an "insidious and invidious" bug...
143 * (Actually the preceding comment is false -- it's the atalk.h in the
144 * ancient atalk-0.06 that's the problem)
145 *
146 * Revision 0.8 1996/02/10 19:09:00 root
147 * Merge 1.3 changes. Tested OK under 1.3.60.
148 *
149 * Revision 0.7 1996/02/10 17:56:56 root
150 * Added debug=1 parameter on insmod for debugging prints. Tried
151 * to fix timer unload on rmmod, but I don't think that's the problem.
152 *
153 * Revision 0.6 1995/12/31 19:01:09 root
154 * Clean up rmmod, irq comments per feedback from Corin Anderson (Thanks Corey!)
155 * Clean up initial probing -- sometimes the card wakes up latched in reset.
156 *
157 * Revision 0.5 1995/12/22 06:03:44 root
158 * Added comments in front and cleaned up a bit.
159 * This version sent out to people.
160 *
161 * Revision 0.4 1995/12/18 03:46:44 root
162 * Return shortDDP to longDDP fake to 0/0. Added command structs.
