|
.Cd "device sf"
|
|
.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.

.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).
