Your question deserves a more detailed answer, but here's an easy part.

Two, one for flows 1, 2, and 4 (since they match on the same bits of the same field), and one for flow 3 (which matches on a different field entirely). The megaflows kernel design is similar to the userspace classifier. The main difference is that overlapping flows aren't allowed, so that any match that is found can be accepted. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
