+![Build Status](https://github.com/safchain/ethtool/actions/workflows/unittests.yml/badge.svg)
+[![GoDoc](https://godoc.org/github.com/safchain/ethtool?status.svg)](https://godoc.org/github.com/safchain/ethtool)
+
+
+The ethtool package aims to provide a library that provides easy access to the Linux SIOCETHTOOL ioctl operations. It can be used to retrieve information from a network device such as statistics, driver related information or even the peer of a VETH interface.
+
+# Installation
+
+```shell
+go get github.com/safchain/ethtool
+```
+
+# How to use
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/safchain/ethtool"
+)
+
+func main() {
+	ethHandle, err := ethtool.NewEthtool()
+	if err != nil {
+		panic(err.Error())
+	}
+	defer ethHandle.Close()
+
+	// Retrieve tx from eth0
+	stats, err := ethHandle.Stats("eth0")
+	if err != nil {
+		panic(err.Error())
+	}
+	fmt.Printf("TX: %d\n", stats["tx_bytes"])
+
+	// Retrieve peer index of a veth interface
+	stats, err = ethHandle.Stats("veth0")
+	if err != nil {
+		panic(err.Error())
+	}
+	fmt.Printf("Peer Index: %d\n", stats["peer_ifindex"])
+}
