36.Sh NAME
37.Nm ste
38.Nd "Sundance Technologies ST201 Fast Ethernet device driver"
39.Sh SYNOPSIS
|
40To compile support for the
41.Nm
42driver into your kernel, place the following lines in your kernel configuration file:
43.Bd -ragged -offset indent |
44.Cd "device miibus"
45.Cd "device ste"
|
46.Ed
47.Pp
48Alternatively, to load the
49.Nm
50driver at boot time, place the following line in
51.Xr loader.conf 5 :
52.Bd -literal -offset indent
53if_ste_load="YES"
54.Ed |
55.Sh DESCRIPTION
56The
57.Nm
58driver provides support for PCI Ethernet adapters and embedded
59controllers based on the Sundance Technologies ST201 PCI Fast
60Ethernet controller chip.
61.Pp
62The Sundance ST201 uses bus master DMA and is designed to be a
633Com Etherlink XL workalike.
64It uses the same DMA descriptor
65structure and is very similar in operation, however its register
66layout is different.
67The ST201 has a 64-bit multicast hash filter
68and a single perfect filter entry for the station address.
69It supports both 10 and 100Mbps speeds in either full or half duplex
70using an MII transceiver.
71.Pp
72The
73.Nm
74driver supports the following media types:
75.Pp
76.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
77.It autoselect
78Enable autoselection of the media type and options.
79The user can manually override
80the autoselected mode by adding media options to the
81.Pa /etc/rc.conf
82file.
83.It 10baseT/UTP
84Set 10Mbps operation.
85The
86.Ar mediaopt
87option can also be used to select either
88.Ar full-duplex
89or
90.Ar half-duplex
91modes.
92.It 100baseTX
93Set 100Mbps (Fast Ethernet) operation.
94The
95.Ar mediaopt
96option can also be used to select either
97.Ar full-duplex
98or
99.Ar half-duplex
100modes.
101.El
102.Pp
103The
104.Nm
105driver supports the following media options:
106.Pp
107.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
108.It full-duplex
109Force full duplex operation
110.It half-duplex
111Force half duplex operation.
112.El
113.Pp
114For more information on configuring this device, see
115.Xr ifconfig 8 .
116.Sh HARDWARE
117The
118.Nm
119driver supports Sundance Technologies ST201 based Fast Ethernet

130.Sh DIAGNOSTICS
131.Bl -diag
132.It "ste%d: couldn't map ports/memory"
133A fatal initialization error has occurred.
134.It "ste%d: couldn't map interrupt"
135A fatal initialization error has occurred.
136.It "ste%d: watchdog timeout"
137The device has stopped responding to the network, or there is a problem with
138the network connection (cable).
139.It "ste%d: no memory for rx list"
140The driver failed to allocate an mbuf for the receiver ring.
141.It "ste%d: no memory for tx list"
142The driver failed to allocate an mbuf for the transmitter ring when
143allocating a pad buffer or collapsing an mbuf chain into a cluster.
144.It "ste%d: chip is in D3 power state -- setting to D0"
145This message applies only to adapters which support power
146management.
147Some operating systems place the controller in low power
148mode when shutting down, and some PCI BIOSes fail to bring the chip
149out of this state before configuring it.
150The controller loses all of
151its PCI configuration in the D3 state, so if the BIOS does not set
152it back to full power mode in time, it will not be able to configure it
153correctly.
154The driver tries to detect this condition and bring
155the adapter back to the D0 (full power) state, but this may not be
156enough to return the driver to a fully operational condition.
157If
158you see this message at boot time and the driver fails to attach
159the device as a network interface, you will have to perform a second
160warm boot to have the device properly configured.
161.Pp
162Note that this condition only occurs when warm booting from another
163operating system.
164If you power down your system prior to booting
165.Fx ,
166the card should be configured correctly.
