Dynamically determines the flow fields that were relevant in processing flows based on the OpenFlow flow table and switch configuration. The immediate use for this functionality is to cache action translations for similar flows in facets. This yields a roughly 80% improvement in flow set up rates for a complicated flow table. More importantly, these wildcards will be used to determine what to wildcard for the forthcoming kernel wildcard (megaflow) patches that will allow wildcarding in the kernel, which will provide significant flow set up improvements. The approach to tracking fields and caching action translations in facets was based on an impressive prototype by Ethan Jackson.
