NAME
ste - Sundance Technologies ST201 Fast Ethernet device driver
SYNOPSIS
device ste* at pci? dev ? function ?
DESCRIPTION
The ste driver provides support for PCI Ethernet adapters and embedded
controllers based on the Sundance Technologies ST201 PCI fast Ethernet
controller chip. This includes the D-Link DFE-550TX.
The Sundance ST201 uses bus master DMA and is designed to be a 3Com
Etherlink XL workalike. It uses the same DMA descriptor structure and is
very similar in operation, however its register layout is different. The
ST201 has a 64-bit multicast hash filter and a single perfect filter en-
try for the station address. IT supports both 10 and 100Mbps speeds in
either full or half duplex using an MII transceiver.
The ste driver supports the following media types:
autoselect Enable autoselection of the media type and options.
The user can manually override the autoselected
mode by adding media options to the hostname.if(5)
file.
10baseT/UTP Set 10Mbps operation. The mediaopt option can also
be used to select either full-duplex or half-duplex
modes.
100baseTX Set 100Mbps (Fast Ethernet) operation. The mediaopt
option can also be used to select either full-
duplex or half-duplex modes.
The ste driver supports the following media options:
full-duplex Force full duplex operation
half-duplex Force half duplex operation.
For more information on configuring this device, see ifconfig(8).
DIAGNOSTICS
ste%d: couldn't map ports/memory A fatal initialization error has oc-
curred.
ste%d: couldn't map interrupt A fatal initialization error has occurred.
ste%d: watchdog timeout The device has stopped responding to the net-
work, or there is a problem with the network connection (cable).
ste%d: no memory for rx list The driver failed to allocate an mbuf for
the receiver ring.
ste%d: no memory for tx list The driver failed to allocate an mbuf for
the transmitter ring when allocating a pad buffer or collapsing an mbuf
chain into a cluster.
ste%d: chip is in D3 power state -- setting to D0 This message applies
only to adapters which support power management. Some operating systems
place the controller in low power mode when shutting down, and some PCI
BIOSes fail to bring the chip out of this state before configuring it.
The controller loses all of its PCI configuration in the D3 state, so if
the BIOS does not set it back to full power mode in time, it won't be
able to configure it correctly. The driver tries to detect this condition
and bring the adapter back to the D0 (full power) state, but this may not
be enough to return the driver to a fully operational condition. If you
see this message at boot time and the driver fails to attach the device
as a network interface, you will have to perform second warm boot to have
the device properly configured.
Note that this condition only occurs when warm booting from another oper-
ating system. If you power down your system prior to booting OpenBSD, the
card should be configured correctly.
