NEP(4)                   BSD Kernel Interfaces Manual                   NEP(4)

NAME
     nep -- Sun Neptune 10Gb Ethernet device

SYNOPSIS
     nep* at pci?
     brgphy* at mii?

DESCRIPTION
     The nep driver provides support for various NICs based on the Sun Neptune
     Ethernet controller chips, including the following:

           o   Sun Quad GBe UTP x8 PCI Express Card
           o   Sun Quad GBe UTP x8 PCIe ExpressModule

     It uses an internal or external PHY or an external 10-bit interface.

     The nep driver supports several media types, which are selected via the
     ifconfig(8) command.  The supported media types are:

           media autoselect
                  Attempt to autoselect the media type (default)

           media 1000baseT mediaopt full-duplex
                  Use 1000baseT on copper, full duplex

           media 1000baseT [mediaopt half-duplex]
                  Use 1000baseT on copper, half duplex

           media 100baseTX mediaopt full-duplex
                  Use 100baseTX, full duplex

           media 100baseTX [mediaopt half-duplex]
                  Use 100baseTX, half duplex

HISTORY
     OpenBSD support for nep first appeared in OpenBSD 5.7.

AUTHORS
     The nep driver was written by Mark Kettenis <kettenis@openbsd.org>.

BUGS
     The nep driver currently only supports 1Gb Ethernet NICs.  It also does
     not yet use many of the advanced features the Neptune chip offers.
