ethtool

ethtool是一个常用的命令行工具，用于配置和查询以太网接口的驱动程序和硬件参数。它提供了一种简单的方式来检查和修改网络接口的设置，以及获取与以太网接口相关的统计数据和状态信息。
ethtool可以执行以下常见的操作：
查询接口信息：使用ethtool命令可以获取以太网接口的各种信息，包括接口名称、连接状态、速度、双工模式、MAC地址、驱动程序信息等。
修改接口参数：ethtool还可以用于修改以太网接口的参数。例如，可以使用ethtool命令设置接口的速度和双工模式，启用或禁用接口的自动协商功能，更改接口的MAC地址等。
查询和重置统计数据：ethtool命令可以获取接口的统计信息，如接收和发送的数据包数量、错误计数等。还可以使用ethtool命令重置这些统计数据。
支持的功能查询：ethtool可以查询网络接口支持的功能列表，如支持的传输速率、双工模式、Wake-on-LAN功能等。
高级功能配置：ethtool还允许对高级功能进行配置，如RSS（接收侧扩展）和TSS（传输侧扩展）等。

请注意，使用ethtool需要root权限或者以root权限运行命令。使用时，可以通过"ethtool <接口名称>"的格式来执行不同的操作。例如，"ethtool eth0"将显示eth0接口的详细信息。

前期准备

.1 Andorid

Android 编译 ethtool 命令

source build/envsetup.sh
lunch rk3568_s-userdebug
mmm external/ethtool/
[ 99% 1005/1006] finishing build rules ...
[100% 1044/1044] Install: out/target/product/rk3568_s/system/bin/ethtool

user 版本需要刷机导入命令，userdebug版本工程机支持命令手动推入到指定目录

adb root
adb remount
adb push X:\xxx\out\target\product\rk3568_s\system\bin\ethtool /system/bin/

.2 Linux

Linux 安装 ethtool 命令

sudo apt-get update
sudo apt-get install ethtool

1. 网口速率设定

查询ethx网口基本设置，其中 x 是对应网卡的编号，如eth0、eth1等等

设置网卡速率
设置网口速率10/100/1000M、设置网口半/全双工、设置网口是否自协商
ethX是以太网卡的名称，Linux系统将检测到的第一块以太网卡命名为eth0, 第二块为eth1。

ethtool -s ethx [speed 10|100|1000] [duplex half|full] [autoneg on|off]

# 设定eth0 10M

# 设定eth0 100M
ethtool -s eth0 speed 100 duplex full autoneg on
# 设定eth0 1G
ethtool -s eth0 speed 1000 duplex full autoneg on
