This driver provides kernel support for Davicom DM9102(A)/DM9132/DM9801 ethernet cards ( CNET
10/100 ethernet cards uses Davicom chipset too, so this driver supports CNET cards too ).If you
didn't compile this driver as a module, it will automatically load itself on boot and print a
line similar to :

A. Compiler command:
dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)

A-1: For normal single or multiple processor kernel
"gcc -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall
-Wstrict-prototypes -O6 -c dmfe.c"
If you compiled this driver as a module, you have to load it on boot.You can load it with command :

A-2: For single or multiple processor with kernel module version function
"gcc -DMODULE -DMODVERSIONS -D__KERNEL__ -I/usr/src/linux/net/inet
-Wall -Wstrict-prototypes -O6 -c dmfe.c"
insmod dmfe

This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
a mode= setting to module while loading, like :

B. The following steps teach you how to activate a DM9102 board:
insmod dmfe mode=0 # Force 10M Half Duplex
insmod dmfe mode=1 # Force 100M Half Duplex
insmod dmfe mode=4 # Force 10M Full Duplex
insmod dmfe mode=5 # Force 100M Full Duplex

1. Used the upper compiler command to compile dmfe.c
Next you should configure your network interface with a command similar to :

2. Insert dmfe module into kernel
"insmod dmfe" ;;Auto Detection Mode (Suggest)
"insmod dmfe mode=0" ;;Force 10M Half Duplex
"insmod dmfe mode=1" ;;Force 100M Half Duplex
"insmod dmfe mode=4" ;;Force 10M Full Duplex
"insmod dmfe mode=5" ;;Force 100M Full Duplex
ifconfig eth0 172.22.3.18
^^^^^^^^^^^
Your IP Adress

3. Config a dm9102 network interface
"ifconfig eth0 172.22.3.18"
^^^^^^^^^^^ Your IP address
Then you may have to modify the default routing table with command :

4. Activate the IP routing table. For some distributions, it is not
necessary. You can type "route" to check.
route add default eth0

"route add default eth0"

Now your ethernet card should be up and running.

5. Well done. Your DM9102 adapter is now activated.

TODO:

C. Object files description:
1. dmfe_rh61.o: For Redhat 6.1
Implement pci_driver::suspend() and pci_driver::resume() power management methods.
Check on 64 bit boxes.
Check and fix on big endian boxes.
Test and make sure PCI latency is now correct for all cases.

If you can make sure your kernel version, you can rename
to dmfe.o and directly use it without re-compiling.
