This directory contains drivers for fast ethernet cards based on the
Adaptec AIC-6915 "Starfire" ethernet controller. The following Adaptec
"Duralink" models are supported:

- ANA-62011 single port 64-bit adapter
- ANA-62022 dual port 64-bit adapter
- ANA-62044 quad port 64-bit adapter
- ANA-69011 single port 32-bit adapter
- ANA-62020 single port 100baseFX

Drivers for FreeBSD 2.2.x, 3.x and 4.0-current are provided. Both FreeBSD/i386
and FreeBSD/alpha are supported.

FREEBSD 2.2.x USERS
-------------------
To add the driver to an existing FreeBSD 2.2.x system, do the following:

- Download if_sf.c and if_sfreg.h from 
  http://www.freebsd.org/~wpaul/Adaptec/2.2 and put them in /sys/pci.
- Edit /sys/conf/files and add a line that says:
pci/if_sf.c             optional sf device-driver
- Edit your kernel config file (e.g. /sys/i386/conf/GENERIC) and add a line
  that says:
device sf0
- Config and compile a new kernel and boot it.

FREEBSD 3.x USERS
-----------------
To add the driver to an existing FreeBSD 3.x system, do the following:

- Download if_sf.c and if_sfreg.h from 
  http://www.freebsd.org/~wpaul/Adaptec/3.0 and put them in /sys/pci.
- Edit /sys/conf/files and add a line that says:
pci/if_sf.c             optional sf device-driver
- Edit your kernel config file (e.g. /sys/i386/conf/GENERIC) and add a line
  that says:
device sf0
- Config and compile a new kernel and boot it.

FREEBSD 4.0-CURRENT USERS
-------------------------

For FreeBSD 4.0, the driver is provided both in source code form and as
a pre-compiled KLD module. This means you have the option of compiling
the driver directly into your kernel, compiling your own module or just
using the pre-compiled module.

TO COMPILE THE DRIVER INTO THE KERNEL:
- Download if_sf.c and if_sfreg.h from 
  http://www.freebsd.org/~wpaul/Adaptec/4.0 and put them in /sys/pci.
- Edit /sys/conf/files and add a line that says:
pci/if_sf.c             optional sf
- Edit your kernel config file (e.g. /sys/i386/conf/GENERIC) and add a line
  that says:
device sf0
- Config and compile a new kernel and boot it.

TO COMPILE THE DRIVER AS A KERNEL MODULE:
- Download if_sf.c, if_sfreg.h and Makefile from
  http://www.freebsd.org/~wpaul/Adaptec/4.0 and put them in a temporary
  directory.
- Type 'make.' This should produce the sf.ko module.
- NOTE: you need the kernel source unpacked in /usr/src/sys in order
  for this to work.

TO LOAD THE PRE-COMPILED KLD MODULE:
- Download sf.ko from http://www.freebsd.org/~wpaul/Adaptec/4.0
  (or compile it yourself, as above) and copy it to /modules.
- Edit /boot/loader.conf and add a line that says:
sf_load="YES"                           # Adaptec PCI ethernet driver
- Reboot

Interfaces should be detected as sf0, sf1, etc... Each port on a multiport
card is a separate interface.

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_sf.c you're using
- The type of system you have (CPU type and speed)
- The exact type of NIC you have
- 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.
