NAME

nve - NVIDIA nForce MCP Networking Adapter device driver

SYNOPSIS

Warning: This driver is deprecated and will not be available in Fx 11.0 and later. Please consider using the nfe(4) driver instead.

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.conf5:

if_nve_load="YES"

DESCRIPTION

The ifconfig 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 ifconfig 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.

1000baseTX

Set 1000Mbps (Gigabit Ethernet) operation.

The ifconfig driver supports the following media options:

full-duplex

Set full duplex operation.

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

HARDWARE

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

• nForce
• nForce2
• nForce3
• nForce4

DIAGNOSTICS

"nve%d: couldn't map memory"

A fatal initialization error has occurred.

"nve%d: couldn't map interrupt"

A fatal initialization error has occurred.

"nve%d: failed to allocate memory"

There are not enough mbufs available for allocation.

"nve%d: device timeout"

The device has stopped responding to the network, or there is a problem with the network connection (cable).

HISTORY

The ifconfig driver first appeared in Fx 6.0 .

BUGS

There are reports that when the card is in auto select mode, ifconfig output reports a 10baseT/UTP output while the LEDs and bandwidth show that the card is actually in 100baseTX mode.
