.Dd $Mdocdate: March 21 2022 $ .Dt NEP 4 .Os .Sh NAME .Nm nep .Nd Sun Neptune 10Gb Ethernet device .Sh SYNOPSIS .Cd "nep* at pci?" .Cd "brgphy* at mii?" .Sh DESCRIPTION The .Nm driver provides support for various NICs based on the Sun Neptune Ethernet controller chips, including the following:
p l -bullet -compact -offset indent t Sun Quad GbE UTP x8 PCI Express Card t Sun Quad GbE UTP x8 PCIe ExpressModule .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 100baseTX Cm mediaopt No full-duplex Use 100baseTX, full duplex t Cm media No 100baseTX Cm mediaopt No half-duplex Use 100baseTX, half duplex .El .Sh SEE ALSO .Xr arp 4 , .Xr brgphy 4 , .Xr ifmedia 4 , .Xr inet 4 , .Xr intro 4 , .Xr netintro 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Sh HISTORY .Ox support for .Nm first appeared in .Ox 5.7 . .Sh AUTHORS The .Nm driver was written by .An Mark Kettenis Aq Mt kettenis@openbsd.org . .Sh BUGS The .Nm driver currently only supports 1Gb Ethernet NICs. It also does not yet use many of the advanced features the Neptune chip offers.
