drivers/net: delete all code/drivers depending on CONFIG_MCA

Browse source 
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.

The intent is to enable the use of different models of FORE adapters at the
same time, by hosts that have several bus interfaces (such as PCI+SBUS,

Only PCI and SBUS devices are currently supported by the driver, but support
for other bus interfaces such as EISA should not be too hard to add (this may
be more tricky for the MCA bus, though, as FORE made some MCA-specific
modifications to the adapter's AALI interface).

This patch was never tested on other MCA-ethernet adapters, but it
might work. Just give it a try and let me know if you have problems.
Also mail me if it really works, please!
Changelog:
Mon Feb 3 16:26:02 MET 1997
- adapted the driver to work with the 2.1.25 kernel
- multiple ne2 support (untested)
- module support (untested)

- fixed a few minor typos
- made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
- fixed the module support (Now it's working...)
Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
- added support for Arco Electronics AE/2-card (experimental)
Mon Sep 14 09:53:42 CET 1998 (David Weinehall)

- Miscellaneous bugfixes
Tue Sep 19 16:21:12 CET 1998 (Magnus Jonsson)
- Cleanup
Wed Sep 23 14:33:34 CET 1998 (David Weinehall)
- Restructuring and rewriting for v2.1.x compliance
Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
- Added code that unregisters irq and proc-info
- Version# bump
Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
- pass 'dev' as last parameter of request_irq in stead of 'NULL'
Wed Feb 7 21:24:00 CET 2001 (Alfred Arnold)
- added support for the D-Link DE-320CT
* WARNING
-------
This is alpha-test software. It is not guaranteed to work. As a
matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
would like to hear from you if you use this driver, even if it works.
If it doesn't work, be sure to send me a mail with the problems !

/* 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.
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.

Verbatim from the Crynwyr stuff:
The 3c523 responds with adapter code 0x6042 at slot
registers xxx0 and xxx1. The setup register is at xxx2 and
contains the following bits:
0: card enable
2,1: csr address select
00 = 0300
01 = 1300
10 = 2300
11 = 3300
4,3: shared memory address select
00 = 0c0000
01 = 0c8000
10 = 0d0000
11 = 0d8000
5: set to disable on-board thinnet
7,6: (read-only) shows selected irq
00 = 12
01 = 7
10 = 3
11 = 9
The interrupt-select register is at xxx3 and uses one bit per irq.
0: int 12
1: int 7
2: int 3
3: int 9
Again, the documentation stresses that the setup register
should never be written. The interrupt-select register may be
written with the value corresponding to bits 7.6 in
the setup register to insure corret setup.

To compile this driver as a module, choose M here. The only
currently supported card is the IBM LAN Adapter/A for Ethernet. It
will both support 16K and 32K memory windows, however a 32K window
gives a better security against packet losses. Usage of multiple
