ewrk3/tulip: Move the DEC - Tulip drivers

Move the DEC - Tulip driver into drivers/net/ethernet/dec/tulip/
and make the necessary Kconfig and Makefile changes.

The Digital Equioment (DEC) driver ewrk3 was moved into
drivers/net/ethernet/dec/ and the remaining drivers (Tulip)
were moved into drivers/net/ethernet/dec/tulip/

-/*  ewrk3.c: A DIGITAL EtherWORKS 3 ethernet driver for Linux.
-
-   Written 1994 by David C. Davies.
-
-   Copyright 1994 Digital Equipment Corporation.
-
-   This software may be used and distributed according to the terms of
-   the GNU General Public License, incorporated herein by reference.
-
-   This driver is written for the Digital Equipment Corporation series
-   of EtherWORKS ethernet cards:
-
-   DE203 Turbo (BNC)
-   DE204 Turbo (TP)
-   DE205 Turbo (TP BNC)
-
-   The driver has been tested on a relatively busy  network using the DE205
-   card and benchmarked with 'ttcp': it transferred 16M  of data at 975kB/s
-   (7.8Mb/s) to a DECstation 5000/200.
-
-   The author may be reached at davies@maniac.ultranet.com.
-
-   =========================================================================
-   This driver has been written  substantially  from scratch, although  its
-   inheritance of style and stack interface from 'depca.c' and in turn from
-   Donald Becker's 'lance.c' should be obvious.
-
-   The  DE203/4/5 boards  all  use a new proprietary   chip in place of the
-   LANCE chip used in prior cards  (DEPCA, DE100, DE200/1/2, DE210, DE422).
-   Use the depca.c driver in the standard distribution  for the LANCE based
-   cards from DIGITAL; this driver will not work with them.
-
-   The DE203/4/5 cards have 2  main modes: shared memory  and I/O only. I/O
-   only makes  all the card accesses through  I/O transactions and  no high
-   (shared)  memory is used. This  mode provides a >48% performance penalty
-   and  is deprecated in this  driver,  although allowed to provide initial
-   setup when hardstrapped.
-
-   The shared memory mode comes in 3 flavours: 2kB, 32kB and 64kB. There is
-   no point in using any mode other than the 2kB  mode - their performances
-   are virtually identical, although the driver has  been tested in the 2kB
-   and 32kB modes. I would suggest you uncomment the line:
-
-   FORCE_2K_MODE;
-
-   to allow the driver to configure the card as a  2kB card at your current
-   base  address, thus leaving more  room to clutter  your  system box with
-   other memory hungry boards.
-
-   As many ISA  and EISA cards  can be supported  under this driver  as you
-   wish, limited primarily  by the available IRQ lines,  rather than by the
-   available I/O addresses  (24 ISA,  16 EISA).   I have  checked different
-   configurations of  multiple  depca cards and  ewrk3 cards  and have  not
-   found a problem yet (provided you have at least depca.c v0.38) ...
-
-   The board IRQ setting   must be at  an unused  IRQ which is  auto-probed
-   using  Donald  Becker's autoprobe  routines.   All  these cards   are at
-   {5,10,11,15}.
-
-   No 16MB memory  limitation should exist with this  driver as DMA is  not
-   used and the common memory area is in low memory on the network card (my
-   current system has 20MB and I've not had problems yet).
-
-   The ability to load  this driver as a  loadable module has been included
-   and used  extensively during the  driver development (to save those long
-   reboot sequences). To utilise this ability, you have to do 8 things:
-
-   0) have a copy of the loadable modules code installed on your system.
-   1) copy ewrk3.c from the  /linux/drivers/net directory to your favourite
-   temporary directory.
-   2) edit the  source code near  line 1898 to reflect  the I/O address and
-   IRQ you're using.
-   3) compile  ewrk3.c, but include -DMODULE in  the command line to ensure
-   that the correct bits are compiled (see end of source code).
-   4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
-   kernel with the ewrk3 configuration turned off and reboot.
-   5) insmod ewrk3.o
-   [Alan Cox: Changed this so you can insmod ewrk3.o irq=x io=y]
-   [Adam Kropelin: now accepts irq=x1,x2 io=y1,y2 for multiple cards]
-   6) run the net startup bits for your new eth?? interface manually
-   (usually /etc/rc.inet[12] at boot time).
-   7) enjoy!
-
-   Note that autoprobing is not allowed in loadable modules - the system is
-   already up and running and you're messing with interrupts.
-
-   To unload a module, turn off the associated interface
-   'ifconfig eth?? down' then 'rmmod ewrk3'.
-
-   Promiscuous   mode has been  turned  off  in this driver,   but  all the
-   multicast  address bits  have been   turned on. This  improved the  send
-   performance on a busy network by about 13%.
-
-   Ioctl's have now been provided (primarily because  I wanted to grab some
-   packet size statistics). They  are patterned after 'plipconfig.c' from a
-   suggestion by Alan Cox.  Using these  ioctls, you can enable promiscuous
-   mode, add/delete multicast  addresses, change the hardware address,  get
-   packet size distribution statistics and muck around with the control and
-   status register. I'll add others if and when the need arises.
