[libvirt] [PATCH 02/10] linkstate: Public API for modifying link state on interfaces
This API adds methods to modify link state of virtual
interfaces of a domain.
Idea of this API is to enable simulation of unplugging
(virtual) cable from the machine to test networks or
to allow propagation of topology changes on the host.
