NAME
Linux::Ethtool - Interface to the Linux SIOCETHTOOL ioctl
SYNOPSIS
use Linux::Ethtool qw(:all);
my $link = get_link("eth0") // die($!);
my $rx_csum = get_rx_csum("eth0") // die($!);
my $tx_csum = get_tx_csum("eth0") // die($!);
print "Link detected: ".($link ? "yes" : "no")."\n";
print "RX checksum offloading: ".($rx_csum ? "yes" : "no")."\n";
print "TX checksum offloading: ".($tx_csum ? "yes" : "no")."\n";
DESCRIPTION
This module provides a procedural interface to the basic operations provided by the Linux SIOCETHTOOL ioctl. The more complex operations that involve getting or setting whole structures at a time are implemented in OO fashion by packages under this namespace.
SUBROUTINES
The following subroutines get or set boolean values on a network interface.
The get functions return defined true/false on success, undef on failure.
The set functions return true on success, false on failure.
get_link($dev) - Link detected
get_rx_csum($dev), set_rx_csum($dev, $enable) - RX checksum offloading enabled
get_tx_csum($dev), set_tx_csum($dev, $enable) - TX checksum offloading enabled
get_sg($dev), set_sg($dev, $enable) - Scatter gather enabled
get_tso($dev), set_tso($dev, $enable) - TCP Segmentation Offload enabled
get_ufo($dev), set_ufo($dev, $enable) - UDP Fragmentation Offload enabled
get_gso($dev), set_gso($dev, $enable) - Generic Segmentation Offload enabled
get_gro($dev), set_gro($dev, $enable) - Generic Receive Offload enabled
