38 .Nd "SiS 900, SiS 7016 and NS DP83815 Fast Ethernet device driver"
45 driver provides support for PCI Ethernet adapters and embedded
46 controllers based on the Silicon Integrated Systems SiS 900
47 and SiS 7016 Fast Ethernet controller chips, including:
49 .Bl -bullet -compact -offset indent
51 @Nifty FNECHARD IFC USUP-TX
55 SiS 630, 635, and 735 motherboard chipsets
58 This driver also supports
59 adapters based on the National Semiconductor DP83815 (MacPhyter)
60 PCI Ethernet controller chip, such as:
62 .Bl -bullet -compact -offset indent
69 The SiS 900 is a 100Mbps Ethernet MAC and MII-compliant transceiver
71 It uses a bus master DMA and a scatter/gather
73 The SiS 7016 is similar to the SiS 900 except
74 that it has no internal PHY, requiring instead an external transceiver
75 to be attached to its MII interface.
76 The SiS 900 and SiS 7016 both have a 128-bit multicast hash filter
77 and a single perfect filter entry for the station address.
79 The NS DP83815 is also a 100Mbps Ethernet MAC with integrated PHY.
80 The NatSemi chip and the SiS 900 share many of the same features and
81 a fairly similar programming interface, hence both chips are supported
86 driver supports the following media types:
88 .Bl -tag -width 10baseTXUTP
90 Enable autoselection of the media type and options.
91 The user can manually override
92 the autoselected mode by adding media options to
99 option can also be used to select either
105 Set 100Mbps (Fast Ethernet) operation.
109 option can also be used to select either
118 driver supports the following media options:
120 .Bl -tag -width full-duplex
122 Force full duplex operation
124 Force half duplex operation.
127 For more information on configuring this device, see
131 .It "sis%d: couldn't map ports/memory"
132 A fatal initialization error has occurred.
133 .It "sis%d: couldn't map interrupt"
134 A fatal initialization error has occurred.
135 .It "sis%d: watchdog timeout"
136 The device has stopped responding to the network, or there is a problem with
137 the network connection (e.g.\& a cable fault).
138 .It "sis%d: no memory for rx list"
139 The driver failed to allocate an mbuf for the receiver ring.
140 .It "sis%d: no memory for tx list"
141 The driver failed to allocate an mbuf for the transmitter ring when
142 allocating a pad buffer or collapsing an mbuf chain into a cluster.
143 .It "sis%d: chip is in D3 power state -- setting to D0"
144 This message applies only to adapters which support power
146 Some operating systems place the controller in low power
147 mode when shutting down, and some PCI BIOSes fail to bring the chip
148 out of this state before configuring it.
149 The controller loses all of
150 its PCI configuration in the D3 state, so if the BIOS does not set
151 it back to full power mode in time, it will not be able to configure it
153 The driver tries to detect this condition and bring
154 the adapter back to the D0 (full power) state, but this may not be
155 enough to return the driver to a fully operational condition.
157 you see this message at boot time and the driver fails to attach
158 the device as a network interface, you will have to perform a
159 warm boot to have the device properly configured.
161 Note that this condition only occurs when warm booting from another
163 If you power down your system prior to booting
165 the card should be configured correctly.
