After looking at both tables (especially the m***_path_add() functions) I think the two tables could be joined. Mesh-nodes could be just a special case where mpp and dst is the same address. The alternative would be to have a flag that states the same thing. I don't even think this would slow down the path_lookup that much, because normally the proxied destinations should be in different hash buckets than the normal ones. Of course cfg80211 would have to deliver both mpp and dst to userspace, I am not quite sure how to do this without breaking compatibility in the output. Maybe an additional netlink command (dump "full" mpath?) would be better than putting more output into the existing one.
