     nve — NVIDIA nForce MCP Networking Adapter device driver


     Warning: This driver is deprecated and will not be available in FreeBSD 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



     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).


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

     ·   nForce
     ·   nForce2
     ·   nForce3
     ·   nForce4


     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).

     The nve driver first appeared in FreeBSD 6.0.


     The nve driver was written by Quinton Dolan <> and David E. O'Brien


     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
