It is useful to be able to see the network addresses in use by a domain for a particular vif in xenstore, for example so that ssh can be invoked by a toolstack to log into the guest domain.
This patch documents paths to allow a domain to advertise MAC (unicast and multicast) and IP (versions 4 and 6) address information.
