NAME
ste —
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:
- D-Link DFE-550TX
- D-Link DFE-580TX
- 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
- ste0: couldn't map ports/memory
- A fatal initialization error has occurred.
- ste0: couldn't map interrupt
- A fatal initialization error has occurred.
- ste0: watchdog timeout
- The device has stopped responding to the network, or there is a problem with the network connection (cable).
- ste0: no memory for rx list
- The driver failed to allocate an mbuf for the receiver ring.
- ste0: 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.
