Hi, There are plenty of examples of fields like this already in struct flow, for instance the OpenFlow metadata and registers. They don't exist in the packet, but adding them to 'struct flow' allows you to program the flow table to match on different values of the field and perform the behaviour that you want. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
