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

•   Sun Quad GbE UTP x8 PCI Express Card
•   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

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

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.
