.Sh NAME
|
|
.Nm nve
|
|
.Nd "NVIDIA nForce MCP Networking Adapter device driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device miibus"
|
|
.Cd "device nve"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_nve_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
This driver is a reimplementation of the NVIDIA supported Linux
|
|
.Nm 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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Bl -tag -width ".Cm 10baseT/UTP"
|
|
.It Cm autoselect
|
|
Enable autoselection of the media type and options.
|
|
.It Cm 10baseT/UTP
|
|
Set 10Mbps operation.
|
|
.It Cm 100baseTX
|
|
Set 100Mbps (Fast Ethernet) operation.
|
|
.It Cm 1000baseTX
|
|
Set 1000Mbps (Gigabit Ethernet) operation.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width ".Cm 10baseT/UTP"
|
|
.It Cm full-duplex
|
|
Set full duplex operation.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver first appeared in
|
|
.Fx 6.0 .

.An -nosplit
|
|
The
|
|
.Nm
|
|
driver was written by
|
|
.An Quinton Dolan Aq q@onthenet.com.au
|
|
and

|
|
.Sh 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.
