SYNOPSIS
device miibus
device sfDESCRIPTION
The sf driver provides support for Adaptec Duralink fast ethernet
adapters based on the Adaptec AIC-6915 "Starfire" chipset. This includes
the following:
· ANA-62011 64-bit single port 10/100baseTX adapter
· ANA-62022 64-bit dual port 10/100baseTX adapter
· ANA-62044 64-bit quad port 10/100baseTX adapter
· ANA-69011 32-bit single port 10/100baseTX adapter
· ANA-62020 64-bit single port 100baseFX adapter
The AIC-6915 is a bus master controller with an MII interface. It sup‐
ports high and low priority transmit and receive queues, TCP/IP checksum
offload, multiple DMA descriptor formats and both polling and pro‐
ducer/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 matching and VLAN
filtering. An external MII-compliant transceiver is required for media
interfacing.
Multiport adapters consist of several AIC-6915 controllers connected via
a PCI to PCI bridge. Each controller is treated as a separate 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 autoselected
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 ifconfig(8).
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 sys‐
tem. The "Plug and Play OS" setting int he BIOS should be set to "no" or
"off" in order for PCI devices to work properly with DragonFly.
sf%d: couldn't map ports A fatal initialization error has occurred.

tem. The "Plug and Play OS" setting int he BIOS should be set to "no" or

sf%d: couldn't map interrupt A fatal initialization error has occurred.
sf%d: no memory for softc struct! The driver failed to allocate 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).
