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.
48 This includes the D-Link DFE-550TX.
50 The Sundance ST201 uses bus master DMA and is designed to be a
51 3Com Etherlink XL workalike.
52 It uses the same DMA descriptor
53 structure and is very similar in operation, however its register
55 The ST201 has a 64-bit multicast hash filter
56 and a single perfect filter entry for the station address.
57 It supports both 10 and 100Mbps speeds in either full or half duplex
58 using an MII transceiver.
62 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:
93 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
95 Force full duplex operation
97 Force half duplex operation.
100 For more information on configuring this device, see
104 .It "ste%d: couldn't map ports/memory"
105 A fatal initialization error has occurred.
106 .It "ste%d: couldn't map interrupt"
107 A fatal initialization error has occurred.
108 .It "ste%d: watchdog timeout"
109 The device has stopped responding to the network, or there is a problem with
110 the network connection (cable).
111 .It "ste%d: no memory for rx list"
112 The driver failed to allocate an mbuf for the receiver ring.
113 .It "ste%d: no memory for tx list"
114 The driver failed to allocate an mbuf for the transmitter ring when
115 allocating a pad buffer or collapsing an mbuf chain into a cluster.
116 .It "ste%d: chip is in D3 power state -- setting to D0"
117 This message applies only to adapters which support power
119 Some operating systems place the controller in low power
120 mode when shutting down, and some PCI BIOSes fail to bring the chip
121 out of this state before configuring it.
122 The controller loses all of
123 its PCI configuration in the D3 state, so if the BIOS does not set
124 it back to full power mode in time, it won't be able to configure it
126 The driver tries to detect this condition and bring
127 the adapter back to the D0 (full power) state, but this may not be
128 enough to return the driver to a fully operational condition.
130 you see this message at boot time and the driver fails to attach
131 the device as a network interface, you will have to perform a second
132 warm boot to have the device properly configured.
134 Note that this condition only occurs when warm booting from another
136 If you power down your system prior to booting
138 the card should be configured correctly.
