drivers/net: delete old parallel port de600/de620 drivers

The parallel port is largely replaced by USB, and even in the
day where these drivers were current, the documented speed was
less than 100kB/s. Let us not pretend that anyone cares about
these drivers anymore, or worse - pretend that anyone is using
them on a modern kernel.

As a side bonus, this is the end of legacy parallel port ethernet,
so we get to drop the whole chunk relating to that in the legacy
Space.c file containing the non-PCI unified probe dispatch.

-
-	1. INTRODUCTION.
-
-	This is a set of Ethernet drivers for the D-Link DE-600/DE-620
-	pocket adapters, for the parallel port on a Linux based machine.
-	Some adapter "clones" will also work.  Xircom is _not_ a clone...
-	These drivers _can_ be used as loadable modules,
-	and were developed for use on Linux 1.1.13 and above.
-	For use on Linux 1.0.X, or earlier releases, see below.
-
-	I have used these drivers for NFS, ftp, telnet and X-clients on
-	remote machines. Transmissions with ftp seems to work as
-	good as can be expected (i.e. > 80k bytes/sec) from a
-	parallel port...:-)  Receive speeds will be about 60-80% of this.
-	Depending on your machine, somewhat higher speeds can be achieved.
-
-	All comments/fixes to Bjorn Ekwall ([e-mail]).

-	3. FILES IN THIS RELEASE.
-
-	README.DLINK  This file.
-	de600.c       The Source (may it be with You :-) for the DE-600
-	de620.c       ditto for the DE-620
-	de620.h       Macros for de620.c
-
-	If you are upgrading from the d-link tar release, there will
-	also be a "dlink-patches" file that will patch Linux 1.1.18:
-		linux/drivers/net/Makefile
-		linux/drivers/net/CONFIG
-		linux/drivers/net/MODULES
-		linux/drivers/net/Space.c
-		linux/config.in
-	Apply the patch by:
-	"cd /usr/src; patch -p0 < linux/drivers/net/dlink-patches"
-	The old source, "linux/drivers/net/d_link.c", can be removed.
-
-
-	4. INSTALLATION.
-
-	o Get the latest net binaries, according to current net.wisdom.
-
-	o Read the NET-2 and Ethernet HOWTOs and modify your setup.
-
-	o If your parallel port has a strange address or irq,
-	  modify "linux/drivers/net/CONFIG" accordingly, or adjust
-	  the parameters in the "tuning" section in the sources.
-
-	If you are going to use the drivers as loadable modules, do _not_
-	enable them while doing "make config", but instead make sure that
-	the drivers are included in "linux/drivers/net/MODULES".
-
-	If you are _not_ going to use the driver(s) as loadable modules,
-	but instead have them included in the kernel, remember to enable
-	the drivers while doing "make config".
-
-	o To include networking and DE600/DE620 support in your kernel:
-	  # cd /linux
-	  (as modules:)
-	  #  make config (answer yes on CONFIG_NET and CONFIG_INET)
-	  (else included in the kernel:)
-	  #  make config (answer yes on CONFIG _NET, _INET and _DE600 or _DE620)
-	  # make clean
-	  # make zImage (or whatever magic you usually do)
-
-	o I use lilo to boot multiple kernels, so that I at least
-	  can have one working kernel :-). If you do too, append
-	  these lines to /etc/lilo/config:
-
-		image = /linux/zImage
-		label = newlinux
-		root = /dev/hda2 (or whatever YOU have...)
-
-	  # /etc/lilo/install
-
-	o Do "sync" and reboot the new kernel with a D-Link
-	  DE-600/DE-620 pocket adapter connected.
-
-	o The adapter can be configured with ifconfig eth?
-	  where the actual number is decided by the kernel
-	  when the drivers are initialized.
-
-
-	5. "PROBLEMS" AND TUNING,
-
-	o If you see error messages from the driver, and if the traffic
-	  stops on the adapter, try to do "ifconfig" and "route" once
-	  more, just as in "rc.inet1".  This should take care of most
-	  problems, including effects from power loss, or adapters that
-	  aren't connected to the printer port in some way or another.
-	  You can somewhat change the behaviour by enabling/disabling
-	  the macro  SHUTDOWN_WHEN_LOST  in the "tuning" section.
-	  For the DE-600 there is another macro, CHECK_LOST_DE600,
-	  that you might want to read about in the "tuning" section.
-
-	o Some machines have trouble handling the parallel port and
-	  the adapter at high speed. If you experience problems:
-
-	  DE-600:
-	  - The adapter is not recognized at boot, i.e. an Ethernet
-	    address of 00:80:c8:... is not shown, try to add another
-	      "; SLOW_DOWN_IO"
-	    at DE600_SLOW_DOWN in the "tuning" section. As a last resort,
-	    uncomment: "#define REALLY_SLOW_IO" (see <asm/io.h> for hints).
-
-	  - You experience "timeout" messages: first try to add another
-	      "; SLOW_DOWN_IO"
-	    at DE600_SLOW_DOWN in the "tuning" section, _then_ try to
-	    increase the value (original value: 5) at
-	    "if (tickssofar < 5)" near line 422.
-
-	  DE-620:
-	  - Your parallel port might be "sluggish".  To cater for
-	    this, there are the macros LOWSPEED and READ_DELAY/WRITE_DELAY
-	    in the "tuning" section. Your first step should be to enable
-	    LOWSPEED, and after that you can "tune" the XXX_DELAY values.
-
-	o If the adapter _is_ recognized at boot but you get messages
-	  about "Network Unreachable", then the problem is probably
-	  _not_ with the driver.  Check your net configuration instead
-	  (ifconfig and route) in "rc.inet1".
-
-	o There is some rudimentary support for debugging, look at
-	  the source. Use "-DDE600_DEBUG=3" or "-DDE620_DEBUG=3"
-	  when compiling, or include it in "linux/drivers/net/CONFIG".
-	  IF YOU HAVE PROBLEMS YOU CAN'T SOLVE: PLEASE COMPILE THE DRIVER
-	  WITH DEBUGGING ENABLED, AND SEND ME THE RESULTING OUTPUT!
-
-
-	6. USING THE DRIVERS WITH EARLIER RELEASES.
-
-	The later 1.1.X releases of the Linux kernel include some
-	changes in the networking layer (a.k.a. NET3). This affects
-	these drivers in a few places.  The hints that follow are
-	_not_ tested by me, since I don't have the disk space to keep
-	all releases on-line.
-	Known needed changes to date:
-	- release patchfile: some patches will fail, but they should
-	  be easy to apply "by hand", since they are trivial.
-	  (Space.c: d_link_init() is now called de600_probe())
-	- de600.c: change  "mark_bh(NET_BH)" to  "mark_bh(INET_BH)".
-	- de620.c: (maybe) change the code around "netif_rx(skb);" to be
-		   similar to the code around "dev_rint(...)" in de600.c
-
-
-	7. ACKNOWLEDGMENTS.
-
-	These drivers wouldn't have been done without the base
-	(and support) from Ross Biro, and D-Link Systems Inc.
-	The driver relies upon GPL-ed source from D-Link Systems Inc.
-	and from Russel Nelson at Crynwr Software <[e-mail]>.
-
-	Additional input also from:
-	Donald Becker <[e-mail]>, Alan Cox <[e-mail]>
-	and Fred N. van Kempen <[e-mail]>
-
-	DE-600 alpha release primary victim^H^H^H^H^H^Htester:
-	- Erik Proper <[e-mail]>.
-	Good input also from several users, most notably
-	- Mark Burton <[e-mail]>.

-	DE-620 alpha release victims^H^H^H^H^H^H^Htesters:
