NAME

casCassini/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 (SX fibre variants)
  • Sun Gigaswift Ethernet (UTP variants)
  • Sun quad Gigaswift Ethernet

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.
