What layer does ifconfig operate at when setting a MTU. Does it set the MTU for the physical device (Network Interface Layer) or the MTU of the packet (Internet Layer)?
ifconfig eth0 mtu 1300
it leads me to believe this is causing the Network Interface Layer to be restricted because an interface must be specified. I am not sure of this though.
Can anyone confirm this for me? Furthermore, if anyone has a good source that would be great!
