sis - SiS 900, SiS 7016, and NS DP83815 Fast Ethernet driver
sis* at pci? dev ? function ?
The sis 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 and FA312.
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.
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.
The sis 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 sis 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).
sis%d: couldn't map ports/memory A fatal initialization error has occurred.
sis%d: couldn't map interrupt A fatal initialization error
has occurred.
sis%d: watchdog timeout The device has stopped responding
to the network,
or there is a problem with the network connection (cable).
sis%d: no memory for rx list The driver failed to allocate
an mbuf for
the receiver ring.
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.
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
won't 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 this message appears at boot time and the driver fails to
attach the
device as a network interface, a second warm boot will have
to be performed
to have the device properly configured.
Note that this condition only occurs when warm booting from
another operating
system. If the system is powered down prior to booting OpenBSD,
the card should be configured correctly.

The sis device driver first appeared in FreeBSD 3.0. OpenBSD support was
added in OpenBSD 2.7.
The sis driver was written by Bill Paul
