PCI Fast Ethernet adapter driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device miibus"
|
|
.Cd "device sf"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_sf_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Adaptec Duralink Fast Ethernet adapters
|
|
based on the Adaptec AIC-6915 "Starfire" chipset.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
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
|
|
.Nm
|
|
driver.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It autoselect
|
|
Enable autoselection of the media type and options.
|
|
The user can manually override
|
|
the autoselected mode by adding media options to the
|
|
.Pa /etc/rc.conf
|
|
file.
|
|
.It 10baseT/UTP
|
|
Set 10Mbps operation.
|
|
The
|
|
.Ar mediaopt
|
|
option can also be used to select either
|
|
.Ar full-duplex
|
|
or
|
|
.Ar half-duplex
|
|
modes.
|
|
.It 100baseTX
|
|
Set 100Mbps (Fast Ethernet) operation.
|
|
The
|
|
.Ar mediaopt
|
|
option can also be used to select either
|
|
.Ar full-duplex
|
|
or
|
|
.Ar half-duplex
|
|
modes.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It full-duplex
|
|
Force full duplex operation
|
|
.It half-duplex
|
|
Force half duplex operation.

.Sh SYSCTL VARIABLES
|
|
The following variables are available as both
|
|
.Xr sysctl 8
|
|
variables and
|
|
.Xr loader 8
|
|
tunables:
|
|
.Bl -tag -width indent
|
|
.It Va dev.sf.%d.int_mod
|
|
Maximum amount of time to delay interrupt processing in units of
|
|
102.4us.
|
|
The accepted range is 0 to 31, the default value is 1 (102.4us).
|
|
Value 0 completely disables the interrupt moderation.
|
|
The interface does not need to be brought down and up again before
|
|
a change takes effect.
|
|
.It Va dev.sf.%d.stats
|
|
Display lots of useful MAC counters maintained in the driver.
|
|
.El
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "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
|
|
.Fx .
|
|
.It "sf%d: couldn't map ports"
|
|
A fatal initialization error has occurred.
|
|

|
|
.It "sf%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "sf%d: no memory for softc struct!"
|
|
The driver failed to allocate memory for per-device instance information
|
|
during initialization.
|
|
.It "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.
|
|
.It "sf%d: watchdog timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (cable).
