Well, we did discuss about structures chained together but for get_mac
and get_mrouters. For get_vbd, get_vlan_interfaces and get_if_list we
decided to return a bitmap or a array of "int ifindex" ([1])
respectively as at that point we did not discuss the difference
between interface names and interface descriptions and thought there
isn't a general need to obtain indexes and names all at once.

Thank you for the information, I'll keep that in mind.
