     sf - Adaptec AIC-6915 Starfire PCI Fast Ethernet driver

SYNOPSIS    [Toc]    [Back]

DESCRIPTION    [Toc]    [Back]

     The sf driver provides support  for  Adaptec  Duralink  Fast
Ethernet
     adapters  based  on the Adaptec AIC-6915 "Starfire" chipset.
This includes
     the following:

           +o   ANA-62011 64-bit single port 10/100baseTX
           +o   ANA-62022 64-bit dual port 10/100baseTX
           +o   ANA-62044 64-bit quad port 10/100baseTX
           +o   ANA-69011 32-bit single port 10/100baseTX
           +o   ANA-62020 64-bit single port 100baseFX

     The AIC-6915 is a bus master controller with an  MII  interface.  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 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    [Toc]    [Back]

     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).
