38 .Nd "SiS 900, SiS 7016 and NS DP83815/DP83816 Fast Ethernet device driver"
40 To compile this driver into the kernel,
41 place the following lines in your
42 kernel configuration file:
43 .Bd -ragged -offset indent
48 Alternatively, to load the driver as a
49 module at boot time, place the following line in
51 .Bd -literal -offset indent
57 driver provides support for PCI Ethernet adapters and embedded
58 controllers based on the Silicon Integrated Systems SiS 900
59 and SiS 7016 Fast Ethernet controller chips.
61 This driver also supports
62 adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816
63 PCI Ethernet controller chip.
65 The SiS 900 is a 100Mbps Ethernet MAC and MII-compliant transceiver
67 It uses a bus master DMA and a scatter/gather
69 The SiS 7016 is similar to the SiS 900 except
70 that it has no internal PHY, requiring instead an external transceiver
71 to be attached to its MII interface.
72 The SiS 900 and SiS 7016 both have a 128-bit multicast hash filter
73 and a single perfect filter entry for the station address.
75 The NS DP83815 is also a 100Mbps Ethernet MAC with integrated PHY.
76 The NatSemi chip and the SiS 900 share many of the same features and
77 a fairly similar programming interface, hence both chips are supported
82 driver supports the following media types:
83 .Bl -tag -width 10baseTXUTP
85 Enable autoselection of the media type and options.
86 The user can manually override
87 the autoselected mode by adding media options to
94 option can also be used to select either
100 Set 100Mbps (Fast Ethernet) operation.
104 option can also be used to select either
113 driver supports the following media options:
114 .Bl -tag -width full-duplex
116 Force full duplex operation.
118 Force half duplex operation.
121 For more information on configuring this device, see
126 driver supports Silicon Integrated Systems SiS 900 and SiS 7016 based
127 Fast Ethernet adapters and embedded controllers, as well as Fast Ethernet
128 adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816
130 Supported adapters include:
134 @Nifty FNECHARD IFC USUP-TX
138 Netgear FA311-TX (DP83815)
140 Netgear FA312-TX (DP83815)
142 SiS 630, 635, and 735 motherboard chipsets
144 Soekris Engineering net45xx, net48xx, lan1621, and lan1641
147 The following variable is available as both
152 .Bl -tag -width indent
153 .It Va dev.sis.%unit.manual_pad
154 This variable controls how to pad short frames for DP83815/DP83816
155 controllers on the specified device.
156 DP83815/DP83816 controllers are known to pad 0xFF for short frames
157 which is violation of RFC 1042.
158 Set this variable to a non-zero value to let driver manually pad
159 each short frame with zeros at the cost of extra CPU cycles.
160 The default value is 0 to let hardware perform automatic padding.
164 .It "sis%d: couldn't map ports/memory"
165 A fatal initialization error has occurred.
166 .It "sis%d: couldn't map interrupt"
167 A fatal initialization error has occurred.
168 .It "sis%d: watchdog timeout"
169 The device has stopped responding to the network, or there is a problem with
170 the network connection (e.g.\& a cable fault).
171 .It "sis%d: no memory for rx list"
172 The driver failed to allocate an mbuf for the receiver ring.
173 .It "sis%d: no memory for tx list"
174 The driver failed to allocate an mbuf for the transmitter ring when
175 allocating a pad buffer or collapsing an mbuf chain into a cluster.
176 .It "sis%d: chip is in D3 power state -- setting to D0"
177 This message applies only to adapters which support power
179 Some operating systems place the controller in low power
180 mode when shutting down, and some PCI BIOSes fail to bring the chip
181 out of this state before configuring it.
182 The controller loses all of
183 its PCI configuration in the D3 state, so if the BIOS does not set
184 it back to full power mode in time, it will not be able to configure it
186 The driver tries to detect this condition and bring
187 the adapter back to the D0 (full power) state, but this may not be
188 enough to return the driver to a fully operational condition.
190 you see this message at boot time and the driver fails to attach
191 the device as a network interface, you will have to perform a
192 warm boot to have the device properly configured.
194 Note that this condition only occurs when warm booting from another
196 If you power down your system prior to booting
198 the card should be configured correctly.
