ste - Sundance Technologies ST201 Fast Ethernet driver
ste* at pci? dev ? function ?
The ste driver provides support for PCI Ethernet adapters
controllers based on the Sundance Technologies ST201 PCI
controller chip. This includes the D-Link DFE-550TX.
The Sundance ST201 uses bus master DMA and is designed to be
EtherLink XL work-alike. It uses the same DMA descriptor
is very similar in operation, however its register layout is
The ST201 has a 64-bit multicast hash filter and a single
entry 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 Set 10Mbps operation. The mediaopt option can
also be used
to select either full-duplex or half-duplex
100baseTX Set 100Mbps (Fast Ethernet) operation. The
can also be used to select either full-duplex
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).
ste%d: couldn't map ports/memory A fatal initialization error has occurred.
ste%d: couldn't map interrupt A fatal initialization error
ste%d: watchdog timeout The device has stopped responding
to the network,
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
able to configure it correctly. The driver tries to detect
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 this message appears at boot time and the driver fails to
device as a network interface, a second warm boot will have
to be performed
to have the device properly configured.
Note that this condition only occurs when warm booting from
system. If the system is powered down prior to booting OpenBSD,
the card should be configured correctly.

The ste device driver first appeared in FreeBSD 3.0. OpenBSD support was
added in OpenBSD 2.7.
The ste driver was written by Bill Paul
