NAME
ste —
Sundance Technologies ST201 fast
ethernet device driver
SYNOPSIS
device miibus
device ste
DESCRIPTION
Theste 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 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).
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 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 DragonFly, the card should be configured correctly.
