	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.
 | 
						|

	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>.
 | 
						|
 | 
						|
