This is what is the Energy Efficient Ethernet.The problem is, that in lot of environments it conflicts with other features and stuff so i really need to disable it.I read that something can be achieved with:ethtool --set-eee eth0 eee offHowever this is the response i have to that command is:Cannot get EEE settings: Operation not supportedIt seems that my nic is not supported by ethtool. By lacks of documentation on internet and the real need of disabling this unuseful feature I wonder: how i can bypass ethtool and disable the feature on my nic ?The nic should be this according lspci -m:03:00.0 Ethernet controller Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller -r15 Gigabyte Technology Co., Ltd MotherboardBasically I'm trying to find a linux way to do what i normally can do under windows in this panel (in the image is an intel nic, but you got the point):
Turn down the Energy Efficient Ethernet (eee) aka Green Ethernet
