Add a pure open source nForce Ethernet driver, under BSDL.

Browse Source 
This driver was ported from OpenBSD by Shigeaki Tagashira
<shigeaki@se.hiroshima-u.ac.jp> and posted at
http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html
It was additionally cleaned up by me.
It is still a work-in-progress and thus is purposefully not in GENERIC.
And it conflicts with nve(4), so only one should be loaded.

.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 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_nfe_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports PCI Ethernet adapters based on the NVIDIA
nForce Media and Communications Processors (MCP), such as
the nForce, nForce 2, nForce 3, CK804, MCP04, MCP51 and MCP55
Ethernet controller chips.
.Pp
The
.Nm
driver supports the following
.Ar media
types:
.Pp
.Bl -tag -width autoselect -compact
.It Cm autoselect
Enable autoselection of the media type and options.
.It Cm 10baseT
Set 10Mbps operation.
.It Cm 100baseTX
Set 100Mbps (Fast Ethernet) operation.
.It Cm 1000baseT
Set 1000Mbps (Gigabit Ethernet) operation (recent models only).
.El
.Sh SEE ALSO
.Xr arp 4 ,
.Xr intro 4 ,
.Xr miibus 4 ,
.Xr netintro 4 ,
.Xr pci 4 ,
.Xr ifconfig 8
.Sh HISTORY
The
.Nm
device driver first appeared in
.Ox 3.9 ,
and then in
.Fx 6.0 .
.Sh AUTHORS
.An -nosplit
The
.Nm
driver was written by
.An Jonathan Gray
.Aq jsg@openbsd.org
and
.An Damien Bergamini
.Aq damien@openbsd.org .
The
.Nm
driver was ported to
.Fx
by
.An Shigeaki Tagashira
