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 (bj0rn@blox.se).

- 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 <nelson@crynwr.com>.
