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.

       1000baseTX   Set 1000Mbps (Gigabit 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

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 nve driver first appeared in FreeBSD 6.0.

AUTHORS

       The  nve  driver  was   written   by   Quinton   Dolan   <q@onthenet.com.au>   and   David   E.   O'Brien
       <obrien@FreeBSD.org>.

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.
