# mt7915.4

`mt7915` — MediaTek IEEE 802.11ax 无线网络驱动

## 名称

`mt7915`

## 概要

`如果已在 rc.conf(5) 中启用 devmatch(8)，则驱动将在无任何用户干预的情况下自动加载。`

`仅在显式禁用自动加载时，才在 rc.conf(5) 中加入以下行以在引导时手动以模块形式加载此驱动：`

```sh
kld_list="${kld_list} if_mt7915"
```

`此驱动应自动加载特定芯片组所需的任何固件。`

`不建议从 loader(8) 加载此驱动。`

## 描述

`mt7915` 驱动为 MediaTek MT7915E 无线网络设备提供支持。`mt7915` 派生自 MediaTek 的 Linux mt76 驱动。

此驱动需要先加载固件才能工作。在加载驱动之前，需要安装来自 `ports/net/wifi-firmware-mt76-kmod` port 的 `wifi-firmware-mt76-kmod` 软件包。否则将无法使用 [ifconfig(8)](/man/man8/ifconfig.8.md) 创建 [wlan(4)](/man/man4/wlan.4.md) 接口。可使用 fwget(8) 安装正确的固件包。

此驱动使用 **linuxkpi\_wlan** 和 **linuxkpi** 兼容框架在 Linux 与原生 FreeBSD 驱动代码之间以及与原生 [net80211(4)](/man/man4/net80211.4.md) 无线协议栈之间进行桥接。

## 硬件

`mt7915` 驱动支持具有以下芯片组的 PCIe 设备：

* MediaTek MT7915E

## 参见

[wlan(4)](/man/man4/wlan.4.md), [networking(7)](/man/man7/networking.7.md), [fwget(8)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man8/fwget.8.md), [ifconfig(8)](/man/man8/ifconfig.8.md), [wpa\_supplicant(8)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man8/wpa_supplicant.8.md)

## 历史

`mt7915` 驱动首次出现于 FreeBSD 14.0。

## 缺陷

诚然。

虽然 `mt7915` 支持 802.11a/b/g/n/ac/ax 模式，但兼容代码目前仅支持 802.11a/b/g 模式。对 802.11n/ac/ax 的支持尚待推出。

## 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/mt7915.4.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.
