The site.node_client_prefix6() is only used internally by the l3roamd protocol. Therefore it is unnecessary to expose it to an administrator. Instead, if node_client_prefix6 is unspecified in the site, generate an IPv6 Unique Local Address prefix from the site domain_seed. This updates the site documentation as well and marks this setting as both optional and deprecated. Note: If you had the node_client_prefix6 specified before and want to use the new autogeneration from the domain_seed instead then this will break compatibility and will need a gluon-scheduled-domain switch.
