.Nd "SiS 900, SiS 7016 and NS DP83815 fast ethernet device driver"
|
|
.Sh SYNOPSIS
|
|
.Cd "device miibus"
|
|
.Cd "device sis"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for PCI ethernet adapters and embedded
|
|
controllers based on the Silicon Integrated Systems SiS 900
|
|
and SiS 7016 fast ethernet controller chips, as well as support
|
|
for adapters based on the National Semiconductor DP83815 (MacPhyter)
|
|
PCI ethernet controller chip, including the Netgear FA311-TX and
|
|
FA312-TX.
|
|
.Pp
|
|
The SiS 900 is a 100Mbps ethernet MAC and MII-compliant transceiver
|
|
in a single package.
|
|
It uses a bus master DMA and a scatter/gather
|
|
descriptor scheme.
|
|
The SiS 7016 is similar to the SiS 900 except
|
|
that it has no internal PHY, requiring instead an external transceiver
|
|
to be attached to its MII interface.
|
|
The SiS 900 and SiS 7016 both have a 128-bit multicast hash filter
|
|
and a single perfect filter entry for the station address.
|
|
.Pp
|
|
The NS DP83815 is also a 100Mbps ethernet MAC with integrated PHY.
|
|
The NatSemi chip and the SiS 900 share many of the same features and
|
|
a fairly similar programming interface, hence both chips are supported
|
|
by the same driver.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Pp
|
|
.Bl -tag -width 10baseTXUTP
|
|
.It autoselect
|
|
Enable autoselection of the media type and options.
|
|
The user can manually override
|
|
the autoselected mode by adding media options to
|
|
.Xr rc.conf 5 .
|
|
.It 10baseT/UTP
|
|
Set 10Mbps operation.
|
|
The
|
|
.Xr ifconfig 8
|
|
.Cm mediaopt
|
|
option can also be used to select either
|
|
.Sq full-duplex
|
|
or
|
|
.Sq half-duplex
|
|
modes.
|
|
.It 100baseTX
|
|
Set 100Mbps (fast ethernet) operation.
|
|
The
|
|
.Xr ifconfig 8
|
|
.Cm mediaopt
|
|
option can also be used to select either
|
|
.Sq full-duplex
|
|
or
|
|
.Sq half-duplex
|
|
modes.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Pp
|
|
.Bl -tag -width full-duplex
|
|
.It full-duplex
|
|
Force full duplex operation
|
|
.It half-duplex
|
|
Force half duplex operation.

|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "sis%d: couldn't map ports/memory"
|
|
A fatal initialization error has occurred.
|
|
.It "sis%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "sis%d: watchdog timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (e.g. a cable fault).
|
|
.It "sis%d: no memory for rx list"
|
|
The driver failed to allocate an mbuf for the receiver ring.
|
|
.It "sis%d: no memory for tx list"
|
|
The driver failed to allocate an mbuf for the transmitter ring when
|
|
allocating a pad buffer or collapsing an mbuf chain into a clusisr.
|
|
.It "sis%d: chip is in D3 power state -- setting to D0"
|
|
This message applies only to adapters which support power
|
|
management.
|
|
Some operating systems place the controller in low power
|
|
mode when shutting down, and some PCI BIOSes fail to bring the chip
|
|
out of this state before configuring it.
|
|
The controller loses all of
|
|
its PCI configuration in the D3 state, so if the BIOS does not set
|
|
it back to full power mode in time, it will not be able to configure it
|
|
correctly.
|
|
The driver tries to detect this condition and bring
|
|
the adapter back to the D0 (full power) state, but this may not be
|
|
enough to return the driver to a fully operational condition.
|
|
If
|
|
you see this message at boot time and the driver fails to attach
|
|
the device as a network interface, you will have to perform a
|
|
warm boot to have the device properly configured.
|
|
.Pp
|
|
Note that this condition only occurs when warm booting from another
|
|
operating system.
|
|
If you power down your system prior to booting
|
|
.Fx ,
|
|
the card should be configured correctly.
