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 under-
     lying 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:

     o	 nForce
     o	 nForce2
     o	 nForce3
     o	 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).

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.
