This set of two patches adds a new field called default_mtu to the configuration area of network devices. The motivation is to allow libvirt to set initial MTU different from 1500 on guests virtual NICs. We also propose to use this new field to report MTU changes by the guest OS to the device to facilitate debugging and mtu tunning. The first patch just clarify the definition of existing fields
