drivers/net: delete all code/drivers depending on CONFIG_MCA
The support for CONFIG_MCA is being removed, since the 20 year old hardware simply isn't capable of meeting today's software demands on CPU and memory resources. This commit removes any MCA specific net drivers, and removes any MCA specific probe/support code from drivers that were doing a dual ISA/MCA role. Cc: "David S. Miller" <davem@davemloft.net> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: netdev@vger.kernel.org Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

52 * WARNING
53 -------
54 This is alpha-test software. It is not guaranteed to work. As a
55 matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
56 would like to hear from you if you use this driver, even if it works.
57 If it doesn't work, be sure to send me a mail with the problems !

1/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
2/*
3 Most of this driver, except for ultramca_probe is nearly
4 verbatim from smc-ultra.c by Donald Becker. The rest is
5 written and copyright 1996 by David Weis, weisd3458@uni.edu
6
7 This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
8
9 This driver uses the cards in the 8390-compatible, shared memory mode.
10 Most of the run-time complexity is handled by the generic code in
11 8390.c.
12
13 This driver enables the shared memory only when doing the actual data
14 transfers to avoid a bug in early version of the card that corrupted
15 data transferred by a AHA1542.
16
17 This driver does not support the programmed-I/O data transfer mode of
18 the EtherEZ. That support (if available) is smc-ez.c. Nor does it
19 use the non-8390-compatible "Altego" mode. (No support currently planned.)
20
21 Changelog:
22
23 Paul Gortmaker : multiple card support for module users.
24 David Weis : Micro Channel-ized it.
25 Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
26 Christopher Turcksin : Changed MCA-probe so that multiple adapters are
27 found correctly (Jul 16, 1997)
28 Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
29 Tom Sightler : Fixed minor detection bug caused by above merge
30 Tom Sightler : Added support for three more Western Digital
31 MCA-adapters
32 Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
33 Hartmut Schmidt : - Modified parameter detection to handle each
34 card differently depending on a switch-list
35 - 'card_ver' removed from the adapter list
36 - Some minor bug fixes

9
10 This is basically Michael Hipp's ni52 driver, with a new probing
11 algorithm and some minor changes to the 82586 CA and reset routines.
12 Thanks a lot Michael for a really clean i82586 implementation! Unless
13 otherwise documented in ni52.c, any bugs are mine.
14
15 Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
16 any way. The ni52 is a lot easier to modify.
17
18 sources:
19 ni52.c
20
21 Crynwr packet driver collection was a great reference for my first
22 attempt at this sucker. The 3c507 driver also helped, until I noticed
23 that ni52.c was a lot nicer.
24
25 EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
26 Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
27 stuff. Information on CardFacts is found in the Ethernet HOWTO.
28 Also see <a href="http://www.3com.com/">
29
30 Microprocessor Communications Support Chips, T.J. Byers, ISBN
31 0-444-01224-9, has a section on the i82586. It tells you just enough
32 to know that you really don't want to learn how to program the chip.
33
34 The original device probe code was stolen from ps2esdi.c
35
36 Known Problems:
37 Since most of the code was stolen from ni52.c, you'll run across the
38 same bugs in the 0.62 version of ni52.c, plus maybe a few because of
39 the 3c523 idiosynchacies. The 3c523 has 16K of RAM though, so there
40 shouldn't be the overrun problem that the 8K ni52 has.
41
42 This driver is for a 16K adapter. It should work fine on the 64K
43 adapters, but it will only use one of the 4 banks of RAM. Modifying
44 this for the 64K version would require a lot of heinous bank
45 switching, which I'm sure not interested in doing. If you try to
46 implement a bank switching version, you'll basically have to remember
47 what bank is enabled and do a switch every time you access a memory
48 location that's not current. You'll also have to remap pointers on
49 the driver side, because it only knows about 16K of the memory.
50 Anyone desperate or masochistic enough to try?
51
52 It seems to be stable now when multiple transmit buffers are used. I
53 can't see any performance difference, but then I'm working on a 386SX.
54
55 Multicast doesn't work. It doesn't even pretend to work. Don't use
56 it. Don't compile your kernel with multicast support. I don't know
57 why.
58
59 Features:
60 This driver is useable as a loadable module. If you try to specify an
61 IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
62 search the MCA slots until it finds a 3c523 with the specified
63 parameters.
64
65 This driver does support multiple ethernet cards when used as a module
66 (up to MAX_3C523_CARDS, the default being 4)
67
68 This has been tested with both BNC and TP versions, internal and
69 external transceivers. Haven't tested with the 64K version (that I
70 know of).
71

2852,1: csr address select
286 00 = 0300
287 01 = 1300

297 00 = 12
298 01 = 7
299 10 = 3

309 Again, the documentation stresses that the setup register

311written with the value corresponding to bits 7.6 in
312the setup register to insure corret setup.

339 3, set BS0 and BS1 to high (of course...)

27/**
28 * DOC: Traps for the unwary
29 *
30 * The diagram (Figure 1-1) and the POS summary disagree with the
31 * "Interrupt Level" section in the manual.
32 *
33 * The manual contradicts itself when describing the minimum number
34 * buffers in the 'configure lists' command.
35 * My card accepts a buffer config of 4/4.
36 *
37 * Setting the SAV BP bit does not save bad packets, but
38 * only enables RX on-card stats collection.
39 *
40 * The documentation in places seems to miss things. In actual fact
41 * I've always eventually found everything is documented, it just
42 * requires careful study.
43 *
44 * DOC: Theory Of Operation
45 *
46 * The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
47 * amount of on board intelligence that housekeeps a somewhat dumber
48 * Intel NIC. For performance we want to keep the transmit queue deep
49 * as the card can transmit packets while fetching others from main
50 * memory by bus master DMA. Transmission and reception are driven by
51 * circular buffer queues.
52 *
53 * The mailboxes can be used for controlling how the card traverses
54 * its buffer rings, but are used only for initial setup in this
55 * implementation. The exec mailbox allows a variety of commands to
56 * be executed. Each command must complete before the next is
57 * executed. Primarily we use the exec mailbox for controlling the
58 * multicast lists. We have to do a certain amount of interesting
59 * hoop jumping as the multicast list changes can occur in interrupt
60 * state when the card has an exec command pending. We defer such
61 * events until the command completion interrupt.
62 *
63 * A copy break scheme (taken from 3c59x.c) is employed whereby
64 * received frames exceeding a configurable length are passed
65 * directly to the higher networking layers without incuring a copy,
66 * in what amounts to a time/space trade-off.
67 *
68 * The card also keeps a large amount of statistical information
69 * on-board. In a perfect world, these could be used safely at no
70 * cost. However, lacking information to the contrary, processing
71 * them without races would involve so much extra complexity as to
72 * make it unworthwhile to do so. In the end, a hybrid SW/HW
73 * implementation was made necessary --- see mc32_update_stats().
74 *
75 * DOC: Notes
76 *
77 * It should be possible to use two or more cards, but at this stage
78 * only by loading two copies of the same module.
79 *
80 * The on-board 82586 NIC has trouble receiving multiple
81 * back-to-back frames and so is likely to drop packets from fast
82 * senders.

1133 * For each completed packet, we will either copy it and pass it up
1134 * the stack or, if the packet is near MTU sized, we allocate
1135 * another buffer and flip the old one up the stack.
1136 *
1137 * We must succeed in keeping a buffer on the ring. If necessary we
1138 * will toss a received packet rather than lose a ring entry. Once
1139 * the first uncompleted descriptor is found, we move the

28 This is a Micro Channel Ethernet adapter. You need to set
29 CONFIG_MCA to use this driver. It is both available as an in-kernel
30 driver and as a module.
31
32 To compile this driver as a module, choose M here. The only
33 currently supported card is the IBM LAN Adapter/A for Ethernet. It
34 will both support 16K and 32K memory windows, however a 32K window
35 gives a better security against packet losses. Usage of multiple
36 boards with this driver should be possible, but has not been tested
37 up to now due to lack of hardware.
