38 .Nd "Sundance Technologies ST201 Fast Ethernet device driver"
45 driver provides support for PCI Ethernet adapters and embedded
46 controllers based on the Sundance Technologies ST201 PCI Fast
47 Ethernet controller chip.
49 The Sundance ST201 uses bus master DMA and is designed to be a
50 3Com Etherlink XL workalike.
51 It uses the same DMA descriptor
52 structure and is very similar in operation, however its register
54 The ST201 has a 64-bit multicast hash filter
55 and a single perfect filter entry for the station address.
56 It supports both 10 and 100Mbps speeds in either full or half duplex
57 using an MII transceiver.
61 driver supports the following media types:
63 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
65 Enable autoselection of the media type and options.
66 The user can manually override
67 the autoselected mode by adding media options to the
74 option can also be used to select either
80 Set 100Mbps (Fast Ethernet) operation.
83 option can also be used to select either
92 driver supports the following media options:
94 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
96 Force full duplex operation
98 Force half duplex operation.

106 driver supports Sundance Technologies ST201 based Fast Ethernet
107 adapters and embedded controllers including:
119 .It "ste%d: couldn't map ports/memory"
120 A fatal initialization error has occurred.
121 .It "ste%d: couldn't map interrupt"
122 A fatal initialization error has occurred.
123 .It "ste%d: watchdog timeout"
124 The device has stopped responding to the network, or there is a problem with
125 the network connection (cable).
126 .It "ste%d: no memory for rx list"
127 The driver failed to allocate an mbuf for the receiver ring.
128 .It "ste%d: no memory for tx list"
129 The driver failed to allocate an mbuf for the transmitter ring when
130 allocating a pad buffer or collapsing an mbuf chain into a cluster.
131 .It "ste%d: chip is in D3 power state -- setting to D0"
132 This message applies only to adapters which support power
134 Some operating systems place the controller in low power
135 mode when shutting down, and some PCI BIOSes fail to bring the chip
136 out of this state before configuring it.
137 The controller loses all of
138 its PCI configuration in the D3 state, so if the BIOS does not set
139 it back to full power mode in time, it will not be able to configure it
141 The driver tries to detect this condition and bring
142 the adapter back to the D0 (full power) state, but this may not be
143 enough to return the driver to a fully operational condition.
145 you see this message at boot time and the driver fails to attach
146 the device as a network interface, you will have to perform a second
147 warm boot to have the device properly configured.
149 Note that this condition only occurs when warm booting from another
151 If you power down your system prior to booting
153 the card should be configured correctly.
