.Dd December 25, 2019 .Dt CAS 4 .Os .Sh NAME .Nm cas .Nd Cassini/Cassini+ (GigaSwift) Ethernet device driver .Sh SYNOPSIS .Cd "cas* at pci? dev ? function ?"
p Configuration of PHYs may also be necessary. See .Xr mii 4 . .Sh DESCRIPTION The .Nm 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.
p Cards supported by this driver include: l -bullet -compact t Sun GigaSwift Ethernet 1.0 MMF (Cassini Kuheen) (part no. 501-5524) t Sun GigaSwift Ethernet 1.0 UTP (Cassini) (part no. 501-5902) t Sun GigaSwift Ethernet UTP (GCS) (part no. 501-6719) t Sun Quad GigaSwift Ethernet UTP (QGE) (part no. 501-6522) t Sun Quad GigaSwift Ethernet PCI-X (QGE-X) (part no. 501-6738) .El .Sh SEE ALSO .Xr brgphy 4 , .Xr gentbi 4 , .Xr gphyter 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr mii 4 , .Xr ifconfig 8 .Rs .%T "Cassini+ ASIC Specification" .%A Sun Microsystems .%U https://web.archive.org/web/20090701014334/http://www.sun.com/processors/manuals/cs_plus.pdf .Re .Sh HISTORY The .Nm driver first appeared in .Ox 4.1 . .Nx support was added in .Nx 6.0 . .Sh AUTHORS .An -nosplit The .Nm driver was written for .Ox by .An Mark Kettenis .Aq kettenis (at] openbsd.org , based on the .Xr gem 4 driver, and ported to .Nx by .An Julian Coleman .Aq jdc (at] NetBSD.org . .Sh BUGS The .Nm driver does not support any of the advanced features of the Cassini chip.
p On the SX fibre variants of the hardware, the link may stay down if media options apart from .Dv autoselect are chosen.
