NVE(4) MidnightBSD Kernel Interfaces Manual NVE(4)

NAME

nve — NVIDIA nForce MCP Networking Adapter device driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device miibus
device nve

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

if_nve_load="YES"

DESCRIPTION

The nve driver provides support for the NVIDIA nForce MCP and nForce2 MCP2 networking adapter that is embedded in the southbridge of most nForce and nForce2 motherboards.

This driver is a reimplementation of the NVIDIA supported Linux nvnet driver and uses the same closed source API library to access the underlying hardware. There is currently no programming documentation available for this device, and therefore little is known about the internal architecture of the MAC engine itself.

The nve driver supports the following media types:

autoselect

Enable autoselection of the media type and options.

10baseT/UTP

Set 10Mbps operation.

100baseTX

Set 100Mbps (Fast Ethernet) operation.

The nve driver supports the following media options:

full-duplex

Set full duplex operation.

For more information on configuring this device, see ifconfig(8).

HARDWARE

The nve driver supports the NVIDIA MCP onboard adapters of mainboards with the following chipsets:

•

nForce

•

nForce2

•

nForce3

•

nForce4
