STE(4) OpenBSD Programmer's Manual STE(4)NAMEste - Sundance Technologies ST201 10/100 Ethernet device
SYNOPSIS
ste* at pci?
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:
o D-Link DFE-550TX
o D-Link DFE-580TX
o Encore ENL832-TX-ICNT 10/100 M PCI
The Sundance ST201 uses bus master DMA and is designed to be a 3Com
EtherLink XL work-alike. 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
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 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
occurred.
ste%d: couldn't map interrupt A fatal initialization error has occurred.
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 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 this message appears at boot time and the driver fails to
attach the 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 another
operating system. If the system is powered down prior to booting
OpenBSD, the card should be configured correctly.
