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

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