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, as well as support
48 for adapters based on the National Semiconductor DP83815 (MacPhyter)
49 PCI ethernet controller chip, including the Netgear FA311-TX and
52 The SiS 900 is a 100Mbps ethernet MAC and MII-compliant transceiver
54 It uses a bus master DMA and a scatter/gather
56 The SiS 7016 is similar to the SiS 900 except
57 that it has no internal PHY, requiring instead an external transceiver
58 to be attached to its MII interface.
59 The SiS 900 and SiS 7016 both have a 128-bit multicast hash filter
60 and a single perfect filter entry for the station address.
62 The NS DP83815 is also a 100Mbps ethernet MAC with integrated PHY.
63 The NatSemi chip and the SiS 900 share many of the same features and
64 a fairly similar programming interface, hence both chips are supported
69 driver supports the following media types:
70 .Bl -tag -width 10baseTXUTP
72 Enable autoselection of the media type and options.
73 The user can manually override
74 the autoselected mode by adding media options to
81 option can also be used to select either
87 Set 100Mbps (fast ethernet) operation.
91 option can also be used to select either
100 driver supports the following media options:
101 .Bl -tag -width full-duplex
103 Force full duplex operation
105 Force half duplex operation.
108 For more information on configuring this device, see
116 .It "sis%d: couldn't map ports/memory"
117 A fatal initialization error has occurred.
118 .It "sis%d: couldn't map interrupt"
119 A fatal initialization error has occurred.
120 .It "sis%d: watchdog timeout"
121 The device has stopped responding to the network, or there is a problem with
122 the network connection (e.g. a cable fault).
123 .It "sis%d: no memory for rx list"
124 The driver failed to allocate an mbuf for the receiver ring.
125 .It "sis%d: no memory for tx list"
126 The driver failed to allocate an mbuf for the transmitter ring when
127 allocating a pad buffer or collapsing an mbuf chain into a clusisr.
128 .It "sis%d: chip is in D3 power state -- setting to D0"
129 This message applies only to adapters which support power
131 Some operating systems place the controller in low power
132 mode when shutting down, and some PCI BIOSes fail to bring the chip
133 out of this state before configuring it.
134 The controller loses all of
135 its PCI configuration in the D3 state, so if the BIOS does not set
136 it back to full power mode in time, it will not be able to configure it
138 The driver tries to detect this condition and bring
139 the adapter back to the D0 (full power) state, but this may not be
140 enough to return the driver to a fully operational condition.
142 you see this message at boot time and the driver fails to attach
143 the device as a network interface, you will have to perform a
144 warm boot to have the device properly configured.
146 Note that this condition only occurs when warm booting from another
148 If you power down your system prior to booting
150 the card should be configured correctly.
