This directory contains drivers for network adapters based on the
VIA Technologies VT3043 "Rhine I" and VT86C100A "Rhine II" ethernet
controller chips, including the following:

- D-Link DFE530-TX
- Hawking Technologies PN102TX

There are probably other cards available with the VIA Rhine
chipset; these just happen to be the two that I have. Note that
the chip on the D-Link card actually says DL10030 on it; D-Link
has changed the markings, but this is still a VIA Rhine II chip.

This driver has been incorporated into FreeBSD-current, but will
be maintained here for those who wish to add driver support to
older versions. The driver will be included with the next 3.x
release.

Here are instructions on how to add the VIA Rhine driver to an
existing FreeBSD system:

- Download the version of if_vr.c and if_vrreg.h that goes with your
  version of FreeBSD. The 3.0 directory contains code for FreeBSD 3.0.
  The 2.2 directory is for FreeBSD 2.2.5, 2.2.6, 2.2.7 and 2.2.8.

- Make sure you have the kernel source unpacked under /usr/src.  

- Copy if_vr.c and if_vrreg.h to /sys/pci.

- Edit /sys/conf/files and add a line that says: 

pci/if_vr.c             optional vr device-driver

- Edit your kernel config file (e.g. /sys/i386/conf/GENERIC) and add
  a line that says: 

device  vr0

- config and compile a new kernel

- copy the kernel to the root directory, then reboot.

Interfaces should be detected as vr0, vr1, etc... You should edit 
/etc/rc.conf to have the interface brought up automatically when the
system boots.

If you experience problems with the driver, please send mail to
wpaul@skynet.ctr.columbia.edu with the following information:

- The version of FreeBSD you're using 
- The rcsid string from the version of if_vr.c you're using
- The type of system you have (CPU type and speed)
- The exact type of NIC you have
- Whether you have an add-in PCI card or if the NIC is built into your
  system somehow (integrated on motherboard or docking station)
- A copy of the dmesg output for your system showing the messages
  where your card is probed
- A complete description of the problem, with error messages if any.
- Optionally, boot your system with the -v flag to obtain verbose boot
  messages and include all the messages related to the rl device.

The copies of the code here may be updated to add fixes. Notices
of new versions will be posted to committers@freebsd.org.
