[rbridge] Should we optimize the common case?

[Guillermo Ibáñez]

You are likely right (DHCP and IPv6 defaul). But it is probably
worth to think a moment how to circunvent it before rejecting the 
approach, given the advantages involved.
Hierarchical addresses are an option to global standard host list 
mechanism, they could be enabled and disabled per RBridge.
