33.Dd October 28, 2006 34.Dt SIS 4 35.Os 36.Sh NAME 37.Nm sis 38.Nd "SiS 900, SiS 7016 and NS DP83815/DP83816 Fast Ethernet device driver" 39.Sh SYNOPSIS 40To compile this driver into the kernel, 41place the following lines in your 42kernel configuration file: 43.Bd -ragged -offset indent 44.Cd "device miibus" 45.Cd "device sis" 46.Ed 47.Pp 48Alternatively, to load the driver as a 49module at boot time, place the following line in 50.Xr loader.conf 5 : 51.Bd -literal -offset indent 52if_sis_load="YES" 53.Ed 54.Sh DESCRIPTION 55The 56.Nm 57driver provides support for PCI Ethernet adapters and embedded 58controllers based on the Silicon Integrated Systems SiS 900 59and SiS 7016 Fast Ethernet controller chips. 60.Pp 61This driver also supports 62adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816 63PCI Ethernet controller chip. 64.Pp 65The SiS 900 is a 100Mbps Ethernet MAC and MII-compliant transceiver 66in a single package. 67It uses a bus master DMA and a scatter/gather 68descriptor scheme. 69The SiS 7016 is similar to the SiS 900 except 70that it has no internal PHY, requiring instead an external transceiver 71to be attached to its MII interface. 72The SiS 900 and SiS 7016 both have a 128-bit multicast hash filter 73and a single perfect filter entry for the station address. 74.Pp 75The NS DP83815 is also a 100Mbps Ethernet MAC with integrated PHY. 76The NatSemi chip and the SiS 900 share many of the same features and 77a fairly similar programming interface, hence both chips are supported 78by the same driver. 79.Pp 80The 81.Nm 82driver supports the following media types: 83.Pp 84.Bl -tag -width 10baseTXUTP 85.It autoselect 86Enable autoselection of the media type and options. 87The user can manually override 88the autoselected mode by adding media options to 89.Xr rc.conf 5 . 90.It 10baseT/UTP 91Set 10Mbps operation. 92The 93.Xr ifconfig 8 94.Cm mediaopt 95option can also be used to select either 96.Sq full-duplex 97or 98.Sq half-duplex 99modes. 100.It 100baseTX 101Set 100Mbps (Fast Ethernet) operation. 102The 103.Xr ifconfig 8 104.Cm mediaopt 105option can also be used to select either 106.Sq full-duplex 107or 108.Sq half-duplex 109modes. 110.El 111.Pp 112The 113.Nm 114driver supports the following media options: 115.Pp 116.Bl -tag -width full-duplex 117.It full-duplex 118Force full duplex operation 119.It half-duplex 120Force half duplex operation. 121.El 122.Pp 123For more information on configuring this device, see 124.Xr ifconfig 8 . 125.Sh HARDWARE 126The 127.Nm 128driver supports Silicon Integrated Systems SiS 900 and SiS 7016 based 129Fast Ethernet adapters and embedded controllers, as well as Fast Ethernet 130adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816 131chips. 132Supported adapters include: 133.Pp 134.Bl -bullet -compact 135.It 136@Nifty FNECHARD IFC USUP-TX 137.It 138MELCO LGY-PCI-TXC 139.It 140Netgear FA311-TX (DP83815) 141.It

"sis%d: couldn't map ports/memory" 151A fatal initialization error has occurred. 152.It "sis%d: couldn't map interrupt" 153A fatal initialization error has occurred. 154.It "sis%d: watchdog timeout" 155The device has stopped responding to the network, or there is a problem with 156the network connection (e.g.\& a cable fault). 157.It "sis%d: no memory for rx list" 158The driver failed to allocate an mbuf for the receiver ring. 159.It "sis%d: no memory for tx list" 160The driver failed to allocate an mbuf for the transmitter ring when 161allocating a pad buffer or collapsing an mbuf chain into a cluster. 162.It "sis%d: chip is in D3 power state -- setting to D0" 163This message applies only to adapters which support power 164management. 165Some operating systems place the controller in low power 166mode when shutting down, and some PCI BIOSes fail to bring the chip 167out of this state before configuring it. 168The controller loses all of 169its PCI configuration in the D3 state, so if the BIOS does not set 170it back to full power mode in time, it will not be able to configure it 171correctly. 172The driver tries to detect this condition and bring 173the adapter back to the D0 (full power) state, but this may not be 174enough to return the driver to a fully operational condition. 175If 176you see this message at boot time and the driver fails to attach 177the device as a network interface, you will have to perform a 178warm boot to have the device properly configured. 179.Pp 180Note that this condition only occurs when warm booting from another 181operating system. 182If you power down your system prior to booting 183.Fx , 184the card should be configured correctly. 185.El 186.Sh SEE ALSO 187.Xr altq 4 , 188.Xr arp 4 , 189.Xr miibus 4 , 190.Xr netintro 4 ,
