# dtsec.4

`dtsec` — 基于 Freescale Datapath Acceleration Architecture 的三速以太网控制器设备驱动

## 名称

`dtsec`

## 概要

`要将此驱动编译进内核，请将以下行放入你的内核配置文件：`

> include dpaa/config.dpaa device dpaa device miibus

## 描述

`dtsec` 驱动为集成在某些 Freescale 片上系统设备中的基于 DPAA 的千兆以太网控制器提供支持。

`dtsec` 驱动支持以下媒体类型：

**autoselect** 启用媒体类型和选项的自动选择

**10baseT/UTP** 设置 10Mbps 操作

**100baseTX** 设置 100Mbps 操作

**1000baseT** 设置 1000baseT 操作

`dtsec` 驱动支持以下媒体选项：

**full-duplex** 设置全双工操作

`dtsec` 驱动支持两种操作模式：

**Regular** 正常模式，利用完整的数据路径加速、缓冲区管理器和队列管理器。

**Independent** 与缓冲区管理器和队列管理器断开运行。

## 硬件

已知以下 Freescale 片上系统设备中内置的千兆以太网控制器可与 `dtsec` 驱动配合工作：

* P2041、P3041
* P5010、P5020

此外，以下设备预期可工作，但未经测试：

* P4080、P4040
* P5040

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/dtsec.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.
