drivers/net: delete old 8 bit ISA Racal ni5010 support. 

These cards were only available in 8bit format, and in addition
they only had AUI and BNC(10-Base2) interfaces (i.e. no RJ-45).

In fact, they are so rare, that an internet search on these old
cards almost comes up empty, unless the "Micom interlan" name
is used.

This puts them in the equivalent domain as the 3c501, so there
should be no strong opposition to the driver removal, as nobody
is seriously using 3.9+ with 8 bit ISA hardware.

In doing so, the whole "ethernet/racal" category becomes empty,
so we clean up the Makefile/Kconfig and subdir appropriately.

config NET_VENDOR_RACAL
bool "Racal-Interlan (Micom) NI devices"
default y
depends on ISA
---help---
If you have a network (Ethernet) card belonging to this class, such
as the NI5010, NI5210 or NI6210, say Y and read the Ethernet-HOWTO,
available from <http://www.tldp.org/docs.html#howto>.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about NI cards. If you say Y, you will be asked for
your specific card in the following questions.
if NET_VENDOR_RACAL
config NI5010
tristate "NI5010 support (EXPERIMENTAL)"
depends on ISA && EXPERIMENTAL && BROKEN_ON_SMP
---help---
If you have a network (Ethernet) card of this type, say Y and read
the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Note that this is still
experimental code.
To compile this driver as a module, choose M here. The module
will be called ni5010.

/* ni5010.c: A network driver for the MiCom-Interlan NI5010 ethercard.
*
* Copyright 1996,1997,2006 Jan-Pascal van Best and Andreas Mohr.
*
* This software may be used and distributed according to the terms
* of the GNU General Public License, incorporated herein by reference.
*
* The authors may be reached as:
* janpascal@vanbest.org andi@lisas.de
*
* Sources:
* Donald Becker's "skeleton.c"
* Crynwr ni5010 packet driver
*
* Changes:
* v0.0: First test version
* v0.1: First working version
* v0.2:
* v0.3->v0.90: Now demand setting io and irq when loading as module
* 970430 v0.91: modified for Linux 2.1.14
* v0.92: Implemented Andreas' (better) NI5010 probe
* 970503 v0.93: Fixed auto-irq failure on warm reboot (JB)
* 970623 v1.00: First kernel version (AM)
* 970814 v1.01: Added detection of onboard receive buffer size (AM)
* 060611 v1.02: slight cleanup: email addresses, driver modernization.
* Bugs:
* - not SMP-safe (no locking of I/O accesses)
* - Note that you have to patch ifconfig for the new /proc/net/dev
* format. It gives incorrect stats otherwise.
*
* To do:
* Fix all bugs :-)
* Move some stuff to chipset_init()
* Handle xmt errors other than collisions
* Complete merge with Andreas' driver
* Implement ring buffers (Is this useful? You can't squeeze
* too many packet in a 2k buffer!)
* Implement DMA (Again, is this useful? Some docs say DMA is
* slower than programmed I/O)
*
* Compile with:
* gcc -O2 -fomit-frame-pointer -m486 -D__KERNEL__ \
* -DMODULE -c ni5010.c
*
* Insert with e.g.:
* insmod ni5010.ko io=0x300 irq=5
