The kernel extracts flow data (struct odp_flow_key) from each received packet and hashes the data using a Jenkins hash. User space maintains a more general flow classifier that supports wildcards. It also uses a Jenkins hash as part of the classifier. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
