Cassini/Cassini+ (GigaSwift)
Ethernet device driver
SYNOPSIS
cas* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See
mii(4).
DESCRIPTION
The
cas driver provides support for the Sun Cassini and
Cassini+ (GigaSwift) and the National Semiconductor Saturn Ethernet hardware
found in Sun UltraSPARC machines and Sun GigaSwift PCI cards.
Cards supported by this driver include:

HISTORY
The
cas driver first appeared in
OpenBSD
4.1.
NetBSD support was added in
NetBSD 6.0.
AUTHORS
The
cas driver was written for
OpenBSD
by
Mark Kettenis ⟨kettenis@openbsd.org⟩,
based on the
gem(4) driver, and
ported to
NetBSD by
Julian
Coleman ⟨jdc@NetBSD.org⟩.
BUGS
The
cas driver does not support any of the advanced features
of the Cassini chip.
On the SX fibre variants of the hardware, the link may stay down if media
options apart from
autoselect
are chosen.
