This module 36 * is as stable, sometimes more stable, than the linux version. (Recent 37 * Linux stability issues seem to be related to some issues with newer 38 * distributions using GCC 3.x, however this don't appear to effect FreeBSD 39 * 5.x). 40 * 41 * In accordance with the NVIDIA distribution license it is necessary to 42 * link this module against the nvlibnet.o binary object included in the 43 * Linux driver source distribution. The binary component is not modified in 44 * any way and is simply linked against a FreeBSD equivalent of the nvnet.c 45 * linux kernel module "wrapper". 46 * 47 * The Linux driver uses a common code API that is shared between Win32 and 48 * i386 Linux. This abstracts the low level driver functions and uses 49 * callbacks and hooks to access the underlying hardware device. By using 50 * this same API in a FreeBSD kernel module it is possible to support the 51 * hardware without breaching the Linux source distributions licensing 52 * requirements, or obtaining the hardware programming specifications. 53 * 54 * Although not conventional, it works, and given the relatively small 55 * amount of hardware centric code, it's hopefully no more buggy than its 56 * linux counterpart. 57 * 58 * NVIDIA now support the nForce3 AMD64 platform, however I have been 59 * unable to access such a system to verify support. However, the code is 60 * reported to work with little modification when compiled with the AMD64 61 * version of the NVIDIA Linux library. All that should be necessary to make 62 * the driver work is to link it directly into the kernel, instead of as a 63 * module, and apply the docs/amd64.diff patch in this source distribution to 64 * the NVIDIA Linux driver source. 65 * 66 * This driver should work on all versions of FreeBSD since 4.9/5.1 as well 67 * as recent versions of DragonFly. 68 * 69 * Written by Quinton Dolan <q@onthenet.com.au> 70 * Portions based on existing FreeBSD network drivers. 71 * NVIDIA API usage derived from distributed NVIDIA NVNET driver source files. 72 */ 73 74#include <sys/cdefs.h> 75__FBSDID("$FreeBSD: head/sys/dev/nve/if_nve.c 199560 2009-11-19 22:14:23Z jhb $");
