This is a followup to the excellent patch which allows static IP address assignment. The problem with that patch is that you can only set the host name and cannot set a FQDN because dnsmasq will, as a security measure, not allow it unless --domain is specified.

This patch adds support for adding <domain name="my.domain" /> to the network config file. With that stanza, one can then use FQDNs on the static host assignments, and this should be the domain reported for any clients that request it. If <domain name .. ./> is not specified in the config file, then there is no change in behaviour.
