Are you maintaining additional tables for the select classifier? Personally I would be very interested in seeing the code as multiple nexthops with load balancing behaviour is one of the few things that the current OVS datapath cannot handle. I would favour if the implementation of it is something that is reusable for the offload API. > 2.

What aspects are not yet covered in the offload API as proposed? _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
