# fwip.4

`fwip` — IP over FireWire 驱动程序

## 名称

`fwip`

## 概要

`要将本驱动程序编译进内核，请在你的内核配置文件中加入以下行：`

> device firewire device fwip

`或者，要在引导时以模块方式加载该驱动程序，请在 loader.conf(5) 中加入以下行：`

```sh
firewire_load="YES"
if_fwip_load="YES"
```

## 描述

`fwip` 驱动程序基于 RFC 2734 和 RFC 3146 中描述的协议，提供标准的 IP over FireWire（IEEE 1394）。

[firewire(4)](/man/man4/firewire.4.md) 和 [fwohci(4)](/man/man4/fwohci.4.md) 驱动程序也必须在内核中配置。

如果使用 `DEVICE_POLLING` 选项编译，本驱动程序还支持 [polling(4)](/man/man4/polling.4.md)。

## 历史

`fwip` 设备驱动程序首次出现于 FreeBSD 5.3。

## 作者

`fwip` 驱动程序和本手册页由 Doug Rabson 编写，基于 Hidetoshi Shimokawa 的早期工作。

## 缺陷

本驱动程序目前不支持用于 FireWire 上多播 IP 的 MCAP 协议。多播数据包被视为广播数据包，这对于大多数简单的多播用途已足够。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/fwip.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
