NAME
- sf - Adaptec AIC-6915 "Starfire" PCI Fast Ethernet adapter
- driver
SYNOPSIS
To compile this driver into the kernel, place the following
lines in your
kernel configuration file:
device miibus
device sf
Alternatively, to load the driver as a module at boot time,
place the
following line in loader.conf(5):
if_sf_load="YES"
DESCRIPTION
- The sf driver provides support for Adaptec Duralink Fast
- Ethernet
adapters based on the Adaptec AIC-6915 "Starfire" chipset. - The AIC-6915 is a bus master controller with an MII inter
- face. It supports high and low priority transmit and receive queues,
- TCP/IP checksum
offload, multiple DMA descriptor formats and both polling - and producer/consumer DMA models. The AIC-6915 receive filtering
- options
include a 16 entry perfect filter, a 512-bit hash table for - multicast
addresses, a 512-bit hash table for priority address match - ing and VLAN
filtering. An external MII-compliant transceiver is re - quired for media
interfacing. - Multiport adapters consist of several AIC-6915 controllers
- connected via
a PCI to PCI bridge. Each controller is treated as a sepa - rate interface
by the sf driver. - The sf driver supports the following media types:
- autoselect Enable autoselection of the media type
- and options.
- The user can manually override the au
- toselected
mode by adding media options to the - /etc/rc.conf
file. - 10baseT/UTP Set 10Mbps operation. The mediaopt
- option can also
- be used to select either full-duplex
- or half-duplex
modes. - 100baseTX Set 100Mbps (Fast Ethernet) operation.
- The
- mediaopt option can also be used to
- select either
full-duplex or half-duplex modes. - The sf driver supports the following media options:
- full-duplex Force full duplex operation
- half-duplex Force half duplex operation.
- For more information on configuring this device, see ifcon
- fig(8).
HARDWARE

+o ANA-62011 64-bit single port 10/100baseTX adapter
+o ANA-62022 64-bit dual port 10/100baseTX adapter
+o ANA-62044 64-bit quad port 10/100baseTX adapter
+o ANA-69011 32-bit single port 10/100baseTX adapter
+o ANA-62020 64-bit single port 100baseFX adapter
DIAGNOSTICS
- sf%d: couldn't map memory A fatal initialization error has
- occurred.
This may happen if the PCI BIOS not configured the device, - which may be
because the BIOS has been configured for a "Plug and Play" - operating system. The "Plug and Play OS" setting in the BIOS should be
- set to "no" or
"off" in order for PCI devices to work properly with FreeB - SD.
- sf%d: couldn't map ports A fatal initialization error has
- occurred.

- sf%d: couldn't map interrupt A fatal initialization error
- has occurred.
- sf%d: no memory for softc struct! The driver failed to al
- locate memory
for per-device instance information during initialization. - sf%d: failed to enable I/O ports/memory mapping! The driver
- failed to
initialize PCI I/O port or shared memory access. This might - happen if
the card is not in a bus-master slot. - sf%d: watchdog timeout The device has stopped responding to
- the network,
or there is a problem with the network connection (cable).
