38 .Nd "Sundance Technologies ST201 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 Sundance Technologies ST201 PCI Fast
59 Ethernet controller chip.
61 The Sundance ST201 uses bus master DMA and is designed to be a
62 3Com Etherlink XL workalike.
63 It uses the same DMA descriptor
64 structure and is very similar in operation, however its register
66 The ST201 has a 64-bit multicast hash filter
67 and a single perfect filter entry for the station address.
68 It supports both 10 and 100Mbps speeds in either full or half duplex
69 using an MII transceiver.
73 driver supports the following media types:
75 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
77 Enable autoselection of the media type and options.
78 The user can manually override
79 the autoselected mode by adding media options to the
86 option can also be used to select either
92 Set 100Mbps (Fast Ethernet) operation.
95 option can also be used to select either
104 driver supports the following media options:
106 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
108 Force full duplex operation
110 Force half duplex operation.
113 For more information on configuring this device, see
118 driver supports Sundance Technologies ST201 based Fast Ethernet
119 adapters and embedded controllers including:
131 .It "ste%d: couldn't map ports/memory"
132 A fatal initialization error has occurred.
133 .It "ste%d: couldn't map interrupt"
134 A fatal initialization error has occurred.
135 .It "ste%d: watchdog timeout"
136 The device has stopped responding to the network, or there is a problem with
137 the network connection (cable).
138 .It "ste%d: no memory for rx list"
139 The driver failed to allocate an mbuf for the receiver ring.
140 .It "ste%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 "ste%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 second
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.
