interface: re-use name and mac address rather than re-retrieving
Getting the MAC address of an interface is actually fairly expensive, and we've already gotten it and stored it into def, so just keep def around a bit longer and retrieve it from there. This reduces the time for "virsh iface-list --all" from 28 to 23 seconds when there are 400 interfaces.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
