NAME

steSundance 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:
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).
