|
|
.Nd "SiS 900, SiS 7016 and NS DP83815/DP83816 Fast Ethernet device 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 sis"
|
|
.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_sis_load="YES"
|
|
.Ed
|
|
.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.
|
|
.Pp
|
|
This driver also supports
|
|
adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816
|
|
PCI Ethernet controller chip.
|
|
.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:
|
|
.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.
|
|

|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width full-duplex
|
|
.It full-duplex
|
|
Force full duplex operation.
|
|
.It half-duplex
|
|
Force half duplex operation.

|
|
.Xr ifconfig 8 .
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports Silicon Integrated Systems SiS 900 and SiS 7016 based
|
|
Fast Ethernet adapters and embedded controllers, as well as Fast Ethernet
|
|
adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816
|
|
chips.
|

.Sh SYSCTL VARIABLES
|
|
The following variable is available as both
|
|
.Xr sysctl 8
|
|
variable and
|
|
.Xr loader 8
|
|
tunable:
|
|
.Bl -tag -width indent
|
|
.It Va dev.sis.%unit.manual_pad
|
|
This variable controls how to pad short frames for DP83815/DP83816
|
|
controllers on the specified device.
|
|
DP83815/DP83816 controllers are known to pad 0xFF for short frames
|
|
which is violation of RFC 1042.
|
|
Set this variable to a non-zero value to let driver manually pad
|
|
each short frame with zeros at the cost of extra CPU cycles.
|
|
The default value is 0 to let hardware perform automatic padding.
|
|
.El
|
|
.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 cluster.
|
|
.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.
