NAME

     sf - Adaptec AIC-6915 Starfire PCI Fast Ethernet driver

SYNOPSIS

     sf* at pci? dev ? function ?

DESCRIPTION

     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
           •   ANA-62022 64-bit dual port 10/100baseTX
           •   ANA-62044 64-bit quad port 10/100baseTX
           •   ANA-69011 32-bit single port 10/100baseTX
           •   ANA-62020 64-bit single port 100baseFX

     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
     producer/consumer DMA models. The AIC-6915 receive filtering options in-
     clude a 16 entry perfect filter, a 512-bit hash table for multicast ad-
     dresses, 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 hostname.if(5) file.

     10baseT      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 did not configure the device, which can
     occur when 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 OpenBSD.

     sf%d: couldn't map ports  A fatal initialization error has occurred. This
     may happen if the PCI BIOS did not configure the device, which can occur
     when 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 OpenBSD.

     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).
