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 documenta
- tion available
for this device, and therefore little is known about the in - ternal 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.
- The nve driver supports the following media options:
- full-duplex Set full duplex operation.
- For more information on configuring this device, see ifcon
- fig(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).
