37 .Sh NAME
38 .Nm ste
39 .Nd "Sundance Technologies ST201 fast ethernet device driver"
40 .Sh SYNOPSIS
41 .Cd "device miibus"
42 .Cd "device ste"
43 .Sh DESCRIPTION
44 The
45 .Nm
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.
50 .Pp
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
55 layout is different.
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.
60 .Pp
61 The
62 .Nm
63 driver supports the following media types:
64 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
65 .It autoselect
66 Enable autoselection of the media type and options.
67 The user can manually override
68 the autoselected mode by adding media options to the
69 .Pa /etc/rc.conf
70 file.
71 .It 10baseT/UTP
72 Set 10Mbps operation.
73 The
74 .Ar mediaopt
75 option can also be used to select either
76 .Ar full-duplex
77 or
78 .Ar half-duplex
79 modes.
80 .It 100baseTX
81 Set 100Mbps (fast ethernet) operation.
82 The
83 .Ar mediaopt
84 option can also be used to select either
85 .Ar full-duplex
86 or
87 .Ar half-duplex
88 modes.
89 .El
90 .Pp
91 The
92 .Nm
93 driver supports the following media options:
94 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
95 .It full-duplex
96 Force full duplex operation
97 .It half-duplex
98 Force half duplex operation.

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