CAS(4) OpenBSD Programmer's Manual CAS(4)NAME
cas - 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:
o Sun GigaSwift Ethernet Adapter (10/100/1000baseT)
o Sun GigaSwift Ethernet MMF Adapter (1000baseSX)
o Sun Quad GigaSwift Ethernet UTP Adapter (10/100/1000baseT)
o Sun Quad GigaSwift PCI-X Adapter (10/100/1000baseT)
o 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

OpenBSD support for cas first appeared in OpenBSD 4.1.
AUTHORS
The cas driver was written by Mark Kettenis <kettenis@openbsd.org> based
on the gem(4) driver.
BUGS
The cas driver does not yet use many of the advanced features the Cassini
chip offers.
