Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

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). + + + 2.

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 <bir7@leland.stanford.edu>, + 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>. + + Additional input also from: + Donald Becker <becker@super.org>, Alan Cox <A.Cox@swansea.ac.uk> + and Fred N. van Kempen <waltje@uWalt.NL.Mugnet.ORG> + + DE-600 alpha release primary victim^H^H^H^H^H^Htester: + - Erik Proper <erikp@cs.kun.nl>. + Good input also from several users, most notably + - Mark Burton <markb@ordern.demon.co.uk>. + + DE-620 alpha release victims^H^H^H^H^H^H^Htesters: + - J.
