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 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. .Pp The .Nm driver supports the following media types: .Bl -tag -width full-duplex .It autoselect Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the .Xr hostname.if 5 file. .It 10baseT 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. .El .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. .El .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Sh DIAGNOSTICS .Bl -diag .It "sis0: couldn't map ports/memory" A fatal initialization error has occurred. .It "sis0: couldn't map interrupt" A fatal initialization error has occurred. .It "sis0: watchdog timeout" The device has stopped responding to the network, or there is a problem with the network connection (cable). .It "sis0: no memory for rx list" The driver failed to allocate an mbuf for the receiver ring. .It "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. .El .Sh SEE ALSO .Xr arp 4 , .Xr icsphy 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr netintro 4 , .Xr nsphyter 4 , .Xr pci 4 , .Xr rlphy 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Rs .%T SiS 900 and SiS 7016 datasheets .%U http://www.sis.com.tw .Re .Rs .%T NatSemi DP83815 and DP83816 datasheets .%U http://www.national.com .Re .Sh HISTORY The .Nm device driver first appeared in .Fx 3.0 . .Ox support was added in .Ox 2.7 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Bill Paul Aq Mt wpaul@ee.columbia.edu and ported to .Ox by .An Aaron Campbell Aq Mt aaron@openbsd.org .
