Methods of changing

The application was prepared for different methods of change the MTU parameter. Now only one is available but in the future it should be changed.

Ifconfig

In this method the program execute shell command:

ifconfig $INTERFACE_NAME mtu $MTU

where $INTERFACE_NAME and $MTU are respectively: name of the interface and the target MTU value from the configuration of app. Naturally the command is being executed as the root user.
