Fair enough (you're in way better position to see the implications).  I
know other bits had moved to library interfaces, so thought I'd make the
suggestion.  Main thing that is worth pointing out is this is moving
away from a single netlink based message interface, and towards a
messaging interface per type (VNLink, Qbg...)
