39 .Nd "Sundance Technologies ST201 fast ethernet device driver"
46 driver provides support for PCI ethernet adapters and embedded
47 controllers based on the Sundance Technologies ST201 PCI fast
48 ethernet controller chip.
49 This includes the D-Link DFE-550TX.
51 The Sundance ST201 uses bus master DMA and is designed to be a
52 3Com Etherlink XL workalike.
53 It uses the same DMA descriptor
54 structure and is very similar in operation, however its register
56 The ST201 has a 64-bit multicast hash filter
57 and a single perfect filter entry for the station address.
58 It supports both 10 and 100Mbps speeds in either full or half duplex
59 using an MII transceiver.
63 driver supports the following media types:
65 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
67 Enable autoselection of the media type and options.
68 The user can manually override
69 the autoselected mode by adding media options to the
76 option can also be used to select either
82 Set 100Mbps (fast ethernet) operation.
85 option can also be used to select either
94 driver supports the following media options:
96 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
98 Force full duplex operation
100 Force half duplex operation.
103 For more information on configuring this device, see
107 .It "ste%d: couldn't map ports/memory"
108 A fatal initialization error has occurred.
109 .It "ste%d: couldn't map interrupt"
110 A fatal initialization error has occurred.
111 .It "ste%d: watchdog timeout"
112 The device has stopped responding to the network, or there is a problem with
113 the network connection (cable).
114 .It "ste%d: no memory for rx list"
115 The driver failed to allocate an mbuf for the receiver ring.
116 .It "ste%d: no memory for tx list"
117 The driver failed to allocate an mbuf for the transmitter ring when
118 allocating a pad buffer or collapsing an mbuf chain into a cluster.
119 .It "ste%d: chip is in D3 power state -- setting to D0"
120 This message applies only to adapters which support power
122 Some operating systems place the controller in low power
123 mode when shutting down, and some PCI BIOSes fail to bring the chip
124 out of this state before configuring it.
125 The controller loses all of
126 its PCI configuration in the D3 state, so if the BIOS does not set
127 it back to full power mode in time, it won't be able to configure it
129 The driver tries to detect this condition and bring
130 the adapter back to the D0 (full power) state, but this may not be
131 enough to return the driver to a fully operational condition.
133 you see this message at boot time and the driver fails to attach
134 the device as a network interface, you will have to perform a second
135 warm boot to have the device properly configured.
137 Note that this condition only occurs when warm booting from another
139 If you power down your system prior to booting
141 the card should be configured correctly.
