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 (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.
