.Dd $Mdocdate: September 8 2021 $ .Dt CAS 4 .Os .Sh NAME .Nm cas .Nd Sun Cassini 10/100/1Gb Ethernet device .Sh SYNOPSIS .Cd "cas* at pci?" .Cd "brgphy* at mii?" .Cd "gentbi* at mii?" .Cd "nsgphy* at mii?" .Sh DESCRIPTION The .Nm driver provides support for various NICs based on the Sun Cassini/Cassini+ and National Semiconductor Saturn Ethernet controller chips, including the following:
p l -bullet -compact -offset indent t Sun GigaSwift Ethernet Adapter (10/100/1000baseT) t Sun GigaSwift Ethernet MMF Adapter (1000baseSX) t Sun Quad GigaSwift Ethernet UTP Adapter (10/100/1000baseT) t Sun Quad GigaSwift PCI-X Adapter (10/100/1000baseT) t Sun Dual Gigabit Ethernet and Dual SCSI/P Adapter (10/100/1000baseT) .El
p It uses an internal or external PHY or an external 10-bit interface.
p The .Nm driver supports several media types, which are selected via the .Xr ifconfig 8 command. The supported media types are: l -tag -width "media" -offset indent t Cm media No autoselect Attempt to autoselect the media type (default) t Cm media No 1000baseT Cm mediaopt No full-duplex Use 1000baseT on copper, full duplex t Cm media No 1000baseT Cm mediaopt No half-duplex Use 1000baseT on copper, half duplex t Cm media No 1000baseSX Cm mediaopt No full-duplex Use 1000baseSX on fiber, full duplex t Cm media No 1000baseSX Cm mediaopt No half-duplex Use 1000baseSX on fiber, half duplex t Cm media No 100baseTX Cm mediaopt No full-duplex Use 100baseTX, full duplex t Cm media No 100baseTX Cm mediaopt No half-duplex Use 100baseTX, half duplex t Cm media No 10baseT Cm mediaopt No full-duplex Use 10baseT, full duplex t Cm media No 10baseT Cm mediaopt No half-duplex Use 10baseT, half duplex .El .Sh SEE ALSO .Xr arp 4 , .Xr brgphy 4 , .Xr gentbi 4 , .Xr ifmedia 4 , .Xr inet 4 , .Xr intro 4 , .Xr netintro 4 , .Xr nsgphy 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Sh HISTORY .Ox support for .Nm first appeared in .Ox 4.1 . .Sh AUTHORS The .Nm driver was written by .An Mark Kettenis Aq Mt kettenis@openbsd.org based on the .Xr gem 4 driver. .Sh BUGS The .Nm driver does not yet use many of the advanced features the Cassini chip offers.
