One:Ethtool settings can be saved through the/etc/sysconfig/network-scripts/ifcfg-ethx file to activate the option the next time the device starts.Example: ethtool-s eth0 speed of duplex full Autoneg offThis instruction sets the eth0 device to full-duplex adaptive at a speed of 100Mbs. To set these parameters eth0 startup, modify the file/etc/sysconfig/network-scripts/ifcfg-eth0, adding the following line:Ethtool_opts= "Speed of duplex full Autoneg off"Workaround Two:Writes the Ethtool settings
