* @short_description: #NmtNewtEntry for MTU entry
*
* #NmtMtuEntry is an #NmtNewtEntry for entering MTU values. It will
* only allow typing numeric characters, and will set its
* #NmtNewtWidget:valid property depending on whether it currently
* contains a valid MTU.
*
* The entry also has an attached #NmtNewtLabel. When the entry value
* is "0", the label will read "(default)". Otherwise it reads "bytes",
* indicating the units used by the entry.
