CAS(4)                       Device Drivers Manual                      CAS(4)

NAME
     cas - 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:
     ⊕   Sun GigaSwift Ethernet 1.0 MMF (Cassini Kuheen) (part no. 501-5524)
     ⊕   Sun GigaSwift Ethernet 1.0 UTP (Cassini) (part no. 501-5902)
     ⊕   Sun GigaSwift Ethernet UTP (GCS) (part no. 501-6719)
     ⊕   Sun Quad GigaSwift Ethernet UTP (QGE) (part no. 501-6522)
     ⊕   Sun Quad GigaSwift Ethernet PCI-X (QGE-X) (part no. 501-6738)

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.
