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:
74 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
76 Enable autoselection of the media type and options.
77 The user can manually override
78 the autoselected mode by adding media options to the
85 option can also be used to select either
91 Set 100Mbps (Fast Ethernet) operation.
94 option can also be used to select either
103 driver supports the following media options:
104 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
106 Force full duplex operation.
108 Force half duplex operation.
111 For more information on configuring this device, see
116 driver supports Sundance Technologies ST201 based Fast Ethernet
117 adapters and embedded controllers including:
128 The following variables are available as both
133 .Bl -tag -width "xxxxxx"
134 .It Va dev.ste.%d.int_rx_mod
135 Maximum number of time to delay RX interrupts.
136 The valid range is 0 to 209712 in units of 1us, the default is
138 The value 0 effectively disables the RX interrupt moderation.
139 The resolution of timer is about 3.2us so finer tuning than
140 3.2us wouldn't be available.
141 The interface does not need to be brought down and up again before
142 a change takes effect.
146 .It "ste%d: couldn't map ports/memory"
147 A fatal initialization error has occurred.
148 .It "ste%d: couldn't map interrupt"
149 A fatal initialization error has occurred.
150 .It "ste%d: watchdog timeout"
151 The device has stopped responding to the network, or there is a problem with
152 the network connection (cable).
153 .It "ste%d: no memory for rx list"
154 The driver failed to allocate an mbuf for the receiver ring.
155 .It "ste%d: no memory for tx list"
156 The driver failed to allocate an mbuf for the transmitter ring when
157 allocating a pad buffer or collapsing an mbuf chain into a cluster.
158 .It "ste%d: chip is in D3 power state -- setting to D0"
159 This message applies only to adapters which support power
161 Some operating systems place the controller in low power
162 mode when shutting down, and some PCI BIOSes fail to bring the chip
163 out of this state before configuring it.
164 The controller loses all of
165 its PCI configuration in the D3 state, so if the BIOS does not set
166 it back to full power mode in time, it will not be able to configure it
168 The driver tries to detect this condition and bring
169 the adapter back to the D0 (full power) state, but this may not be
170 enough to return the driver to a fully operational condition.
172 you see this message at boot time and the driver fails to attach
173 the device as a network interface, you will have to perform a second
174 warm boot to have the device properly configured.
176 Note that this condition only occurs when warm booting from another
178 If you power down your system prior to booting
180 the card should be configured correctly.
