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!

+The EtherWORKS 3 driver in this distribution is designed to work with all
+kernels > 1.1.33 (approx) and includes tools in the 'ewrk3tools'
+subdirectory to allow set up of the card, similar to the MSDOS
+'NICSETUP.EXE' tools provided on the DOS drivers disk (type 'make' in that
+subdirectory to make the tools).
+
+The supported cards are DE203, DE204 and DE205. All other cards are NOT
+supported - refer to 'depca.c' for running the LANCE based network cards and
+'de4x5.c' for the DIGITAL Semiconductor PCI chip based adapters from
+Digital.
+
+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: Multiple cards now supported by irq=x1,x2 io=y1,y2]
+ 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'.
+
+The performance we've achieved so far has been measured through the 'ttcp'
+tool at 975kB/s. This measures the total TCP stack performance which
+includes the card, so don't expect to get much nearer the 1.25MB/s
+theoretical Ethernet rate.
+
+
+Enjoy!
