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

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).
