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