Is there a reason why iface is allowed to be paired only with net to create an ipset?
I think with feature of skbinfo in every ipset, it should be allowed to add iface in all ipset. As skbinfo can store tc classes, it might make more sense if I can pin point on which outgoing interface this class should be applied. One direct way of doing could be adding iface in skbinfo itself, but I dont think its a good suggestion. So, other thing left is to have ipset storing interface too. Besides, when I create a tc class, I create it on a known interface, so I know beforehand on which interface this class is created. So I can easily specify while adding entry in ipset.
