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.
59 supports both 10 and 100Mbps speeds in either full or half duplex
60 using an MII transceiver.
64 driver supports the following media types:
66 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
68 Enable autoselection of the media type and options.
69 The user can manually override
70 the autoselected mode by adding media options to the
77 option can also be used to select either
83 Set 100Mbps (fast ethernet) operation.
86 option can also be used to select either
95 driver supports the following media options:
97 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
99 Force full duplex operation
101 Force half duplex operation.
104 For more information on configuring this device, see
108 .It "ste%d: couldn't map ports/memory"
109 A fatal initialization error has occurred.
110 .It "ste%d: couldn't map interrupt"
111 A fatal initialization error has occurred.
112 .It "ste%d: watchdog timeout"
113 The device has stopped responding to the network, or there is a problem with
114 the network connection (cable).
115 .It "ste%d: no memory for rx list"
116 The driver failed to allocate an mbuf for the receiver ring.
117 .It "ste%d: no memory for tx list"
118 The driver failed to allocate an mbuf for the transmitter ring when
119 allocating a pad buffer or collapsing an mbuf chain into a cluster.
120 .It "ste%d: chip is in D3 power state -- setting to D0"
121 This message applies only to adapters which support power
123 Some operating systems place the controller in low power
124 mode when shutting down, and some PCI BIOSes fail to bring the chip
125 out of this state before configuring it.
126 The controller loses all of
127 its PCI configuration in the D3 state, so if the BIOS does not set
128 it back to full power mode in time, it won't be able to configure it
130 The driver tries to detect this condition and bring
131 the adapter back to the D0 (full power) state, but this may not be
132 enough to return the driver to a fully operational condition.
134 you see this message at boot time and the driver fails to attach
135 the device as a network interface, you will have to perform second
136 warm boot to have the device properly configured.
138 Note that this condition only occurs when warm booting from another
140 If you power down your system prior to booting
142 the card should be configured correctly.
