============================================================== Davicom DM9102(A)/DM9132/DM9801 fast ethernet driver for Linux

Note: This driver doesn't have a maintainer.

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::

dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)

If you compiled this driver as a module, you have to load it on boot.You can load it with command::

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::

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

Next you should configure your network interface with a command similar to::

ifconfig eth0 172.22.3.18
	      ^^^^^^^^^^^
	     Your IP Address

Then you may have to modify the default routing table with command::

route add default eth0

Now your ethernet card should be up and running.

TODO:

  • 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.
