31 * NVIDIA nForce MCP Networking Adapter driver
33 * This is a port of the NVIDIA MCP Linux ethernet driver distributed by NVIDIA
34 * through their web site.
36 * All mainstream nForce and nForce2 motherboards are supported. This module
37 * is as stable, sometimes more stable, than the linux version. (This seems to
38 * be related to some issues with newer distributions using GCC 3.2, however
39 * this don't appear to effect FreeBSD 5.x).
41 * In accordance with the NVIDIA distribution license it is necessary to link
42 * this module against the nvlibnet.o binary object included in the Linux
43 * driver source distribution. The binary component is not modified in any
44 * way and is simply linked against a FreeBSD equivalent of the nvnet.c linux
45 * kernel module "wrapper".
47 * The Linux driver uses a common code API that is shared between Win32 and
48 * Linux. This abstracts the low level driver functions and uses callbacks
49 * and hooks to access the underlying hardware device. By using this same API
50 * in a FreeBSD kernel module it is possible to support the hardware without
51 * breaching the Linux source distributions licensing requirements, or
52 * obtaining the hardware programming specifications.
54 * Although not conventional, it works, and given the relatively small amount of
55 * hardware centric code, it's hopefully no more buggy than its linux
58 * Written by Quinton Dolan <q@onthenet.com.au>
59 * Portions based on existing FreeBSD network drivers.
60 * NVIDIA API usage derived from distributed NVIDIA NVNET driver source files.
