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 dri-
     ver 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 out-
     put reports a 10baseT/UTP output while the LEDs and bandwidth show that the
     card is actually in 100baseTX mode.
