NAME
sis —
SiS 900, SiS 7016, and NS DP83815/6
10/100 Ethernet device
SYNOPSIS

DESCRIPTION
The sis driver provides support for PCI
Ethernet adapters and embedded controllers based on the Silicon Integrated
Systems SiS 900 / SiS 7016 Fast Ethernet controller chips, and National
Semiconductor DP83815 (MacPHYTER) / DP83816 (MacPHYTER-II) PCI Ethernet
controller chips, including the following:
- @Nifty FNECHARD IFC USUP-TX
- MELCO LGY-PCI-TXC
- Netgear FA311, FA312, FA331
- Soekris Engineering lan1621, lan1641
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 and DP83816 are also 100Mbps Ethernet MACs with integrated PHY. The NatSemi chips and the SiS chips share many of the same features and a fairly similar programming interface, and hence 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).
DIAGNOSTICS
- sis0: couldn't map ports/memory
- A fatal initialization error has occurred.
- sis0: couldn't map interrupt
- A fatal initialization error has occurred.
- sis0: watchdog timeout
- The device has stopped responding to the network, or there is a problem with the network connection (cable).
- sis0: no memory for rx list
- The driver failed to allocate an mbuf for the receiver ring.
- sis0: 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.
