.Sh NAME
|
|
.Nm nfe
|
|
.Nd "NVIDIA nForce MCP Ethernet 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 nfe"
|
|
.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_nfe_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|

|
|
nForce Media and Communications Processors (MCP), such as
|
|
the nForce, nForce 2, nForce 3, CK804, MCP04, MCP51, MCP55,
|
|
MCP61, MCP65, MCP67, MCP73, MCP77 and MCP79 Ethernet
|
|
controller chips.

Jumbo Frames
|
|
.El
|
|
.Pp
|
|
Support for Jumbo Frames is provided via the interface MTU setting.
|
|

|
|
.Xr ifconfig 8
|
|
utility configures the adapter to receive and transmit Jumbo Frames.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Bl -tag -width "10baseT/UTP"

|
|
Set 100Mbps (Fast Ethernet) operation.
|
|
.It Cm 1000baseT
|
|
Set 1000Mbps (Gigabit Ethernet) operation (recent models only).
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width ".Cm 10baseT/UTP"
|
