Create capture dissector tables.
They are modeled after dissection dissector tables, but for the moment, don't have/need the flexibility. They are intended to be much simpler/faster than full dissection.
The two most used/needed are "wtap_encap" and "ethertype", so they were the basis of starting to use and test capture dissector table API. Others may be added in the future.
The "capture dissector" function signature needed a bit of tweeking to handling "claiming" of a packet.
The current application of this is capture functions returning TRUE if they affected a "type" of packet count. Returning FALSE ends up considering the packet an "other" type.
