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>

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

+ Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
Verified to work with up to 2 DE212 cards in a system (although not
fully stress-tested).
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.

- net-3-driver for the 3c523 Etherlink/MC card (i82586 Ethernet chip)
-
-
- This is an extension to the Linux operating system, and is covered by the
- same GNU General Public License that covers that work.
-
- Copyright 1995, 1996 by Chris Beauregard (cpbeaure@undergrad.math.uwaterloo.ca)
-
- This is basically Michael Hipp's ni52 driver, with a new probing
- algorithm and some minor changes to the 82586 CA and reset routines.
- Thanks a lot Michael for a really clean i82586 implementation! Unless
- otherwise documented in ni52.c, any bugs are mine.
-
- Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
- any way. The ni52 is a lot easier to modify.
-
- sources:
- ni52.c
-
- Crynwr packet driver collection was a great reference for my first
- attempt at this sucker. The 3c507 driver also helped, until I noticed
- that ni52.c was a lot nicer.
-
- EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
- Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
- stuff. Information on CardFacts is found in the Ethernet HOWTO.
- Also see <a href="http://www.3com.com/">
-
- Microprocessor Communications Support Chips, T.J. Byers, ISBN
- 0-444-01224-9, has a section on the i82586. It tells you just enough
- to know that you really don't want to learn how to program the chip.
-
- The original device probe code was stolen from ps2esdi.c
-
- Known Problems:
- Since most of the code was stolen from ni52.c, you'll run across the
- same bugs in the 0.62 version of ni52.c, plus maybe a few because of
- the 3c523 idiosynchacies. The 3c523 has 16K of RAM though, so there
- shouldn't be the overrun problem that the 8K ni52 has.
-
- This driver is for a 16K adapter. It should work fine on the 64K
- adapters, but it will only use one of the 4 banks of RAM. Modifying
- this for the 64K version would require a lot of heinous bank
- switching, which I'm sure not interested in doing. If you try to
- implement a bank switching version, you'll basically have to remember
- what bank is enabled and do a switch every time you access a memory
- location that's not current. You'll also have to remap pointers on
- the driver side, because it only knows about 16K of the memory.
- Anyone desperate or masochistic enough to try?
-
- It seems to be stable now when multiple transmit buffers are used. I
- can't see any performance difference, but then I'm working on a 386SX.
-
- Multicast doesn't work. It doesn't even pretend to work. Don't use
- it. Don't compile your kernel with multicast support. I don't know
- why.
-
- Features:
- This driver is useable as a loadable module. If you try to specify an
- IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
- search the MCA slots until it finds a 3c523 with the specified
- parameters.
-
- This driver does support multiple ethernet cards when used as a module
- (up to MAX_3C523_CARDS, the default being 4)
-
- This has been tested with both BNC and TP versions, internal and
- external transceivers. Haven't tested with the 64K version (that I
- know of).
-
- History:
- Jan 1st, 1996
- first public release
- Feb 4th, 1996
- update to 1.3.59, incorporated multicast diffs from ni52.c
- Feb 15th, 1996
- added shared irq support
- Apr 1999
- added support for multiple cards when used as a module
- added option to disable multicast as is causes problems
- Ganesh Sittampalam <ganesh.sittampalam@magdalen.oxford.ac.uk>
- Stuart Adamson <stuart.adamson@compsoc.net>
- Nov 2001
- added support for ethtool (jgarzik)

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