I need to do this for many IP addresses. What I am trying to do here is to replicate the Modelnet bitflip behaviour where the 23rd bit of the source and destination addresses are flipped [10.128.0.1 -> 10.0.0.1]. So out of the options I have for achieving this: 1. modifying the source code 2. using the registers you mentioned above 3. using a controller and then flipping the bits where required which one do you recommend that I go with? _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
