本文提供了开始使用Linux®命令工具ethtool所需的基本信息。
简介
ethtool允许查询或控制网络驱动程序和硬件设置,尤其是对于有线以太网设备。
安装此工具到开发板上
手动编译安装
使用buildroot
- ethtool已默认安装到开发板文件系统里。
Board $> which ethtool /usr/sbin/ethtool
使用yocto
- 需将此菜谱文件包含进需要构建的系统镜像内
RDEPENDS_packagegroup-framework-tools-network-base = "\ ethtool \ iproute2 \ "
开始使用
可以使用Linux IP命令行列出开发板上可用的以太网链接。
Board $> ip link | grep eth 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 00:80:e1:42:43:65 brd ff:ff:ff:ff:ff:ff
