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

124For more information on configuring this device, see
125.Xr ifconfig 8 .
126.Sh HARDWARE
127The
128.Nm
129driver supports Silicon Integrated Systems SiS 900 and SiS 7016 based
130Fast Ethernet adapters and embedded controllers, as well as Fast Ethernet
131adapters based on the National Semiconductor DP83815 (MacPhyter) chip.

146.Sh DIAGNOSTICS
147.Bl -diag
148.It "sis%d: couldn't map ports/memory"
149A fatal initialization error has occurred.
150.It "sis%d: couldn't map interrupt"
151A fatal initialization error has occurred.
152.It "sis%d: watchdog timeout"
153The device has stopped responding to the network, or there is a problem with
154the network connection (e.g.\& a cable fault).
155.It "sis%d: no memory for rx list"
156The driver failed to allocate an mbuf for the receiver ring.
157.It "sis%d: no memory for tx list"
158The driver failed to allocate an mbuf for the transmitter ring when
159allocating a pad buffer or collapsing an mbuf chain into a cluster.
160.It "sis%d: chip is in D3 power state -- setting to D0"
161This message applies only to adapters which support power
162management.
163Some operating systems place the controller in low power
164mode when shutting down, and some PCI BIOSes fail to bring the chip
165out of this state before configuring it.
166The controller loses all of
167its PCI configuration in the D3 state, so if the BIOS does not set
168it back to full power mode in time, it will not be able to configure it
169correctly.
170The driver tries to detect this condition and bring
171the adapter back to the D0 (full power) state, but this may not be
172enough to return the driver to a fully operational condition.
173If
174you see this message at boot time and the driver fails to attach
175the device as a network interface, you will have to perform a
176warm boot to have the device properly configured.
177.Pp
178Note that this condition only occurs when warm booting from another
179operating system.
180If you power down your system prior to booting
181.Fx ,
182the card should be configured correctly.
