NAME
ste - Sundance Technologies ST201 Fast Ethernet device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
device miibus
device ste
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
if_ste_load="YES"
DESCRIPTION
The ste driver provides support for PCI Ethernet adapters and embedded
controllers based on the Sundance Technologies ST201 PCI Fast Ethernet
controller chip.
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
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 /etc/rc.conf
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).
HARDWARE
The ste driver supports Sundance Technologies ST201 based Fast Ethernet
adapters and embedded controllers including:
· D-Link DFE-530TXS
· D-Link DFE-550TX
· D-Link DFE-580TX
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 will not 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 a
second warm boot to have the device properly configured.
Note that this condition only occurs when warm booting from another
operating system. If you power down your system prior to booting
FreeBSD, the card should be configured correctly.
