Sun Cassini 10/100/Gigabit Ethernet
device
SYNOPSIS
cas* at pci?
brgphy* at mii?
gentbi* at mii?
nsgphy* at mii?
DESCRIPTION
The cas driver provides support for
various NICs based on the Sun Cassini/Cassini+ and National Semiconductor
Saturn Ethernet controller chips, including the following:
- Sun GigaSwift Ethernet Adapter (10/100/1000baseT)
- Sun GigaSwift Ethernet MMF Adapter (1000baseSX)
- Sun Quad GigaSwift Ethernet UTP Adapter (10/100/1000baseT)
- Sun Quad GigaSwift PCI-X Adapter (10/100/1000baseT)
- Sun Dual Gigabit Ethernet and Dual SCSI/P Adapter (10/100/1000baseT)
It uses an internal or external PHY or an external 10-bit interface.
The cas driver supports several media
types, which are selected via the
ifconfig(8) command. The supported media types are:
- media autoselect
- Attempt to autoselect the media type (default)
- media 1000baseT mediaopt full-duplex
- Use 1000baseT on copper, full duplex
- media 1000baseT [mediaopt half-duplex]
- Use 1000baseT on copper, half duplex
- media 1000baseSX mediaopt full-duplex
- Use 1000baseSX on fiber, full duplex
- media 1000baseSX [mediaopt half-duplex]
- Use 1000baseSX on fiber, half duplex
- media 100baseTX mediaopt full-duplex
- Use 100baseTX, full duplex
- media 100baseTX [mediaopt half-duplex]
- Use 100baseTX, half duplex
- media 10baseT mediaopt full-duplex
- Use 10baseT, full duplex
- media 10baseT [mediaopt half-duplex]
- Use 10baseT, half duplex

HISTORY
OpenBSD support for
cas first appeared in OpenBSD
4.1.

based on the gem(4) driver.
BUGS
The cas driver does not yet use many of
the advanced features the Cassini chip offers.
