Ethtool

1. Article purpose[edit source]

This article provides the basic information needed to start using the Linux® command tool: ethtool [1].

2. Introduction[edit source]

The following table provides a brief description of the tool, as well as its availability depending on the software packages:

Yes: this tool is either present (ready to use or to be activated), or can be integrated and activated on the software package.

No: this tool is not present and cannot be integrated, or it is present but cannot be activated on the software package.

Tool STM32MPU Embedded Software distribution STM32MPU Embedded Software distribution for Android™
Name Category Purpose Starter Package Developer Package Distribution Package Starter Package Developer Package Distribution Package
ethtool Monitoring tools ethtool[1] allows to query or control network driver and hardware settings, in particular for wired Ethernet devices. Yes Yes Yes No No No

3. Installing the trace and debug tool on your target board[edit source]

3.1. Using the STM32MPU Embedded Software distribution[edit source]

ethtool is installed by default and ready to be used with all STM32MPU Embedded Software Packages.

 which ethtool
/usr/sbin/ethtool

It is integrated in weston image distribution through the meta-st package: meta-st/meta-st-openstlinux/recipes-st/packagegroups/packagegroup-framework-tools.bb.

RDEPENDS_packagegroup-framework-tools-network-base = "\
   ethtool         \
   iproute2        \
   "

4. Getting started[edit source]

The ethernet links available on your board can be listed by using the IP Linux command line:

 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
  • Get information about the eth0 network device:
 ethtool eth0
