  Log:
  Wildcard matching is tricky - you have to try wildcarding both the
  source *and* destination port and/or both the source *and* destination
  address passed to "find_conversation()", because the packet for which
  you're trying to find the conversation may be going in the opposite
  direction to the packet for which the conversation was originally
  created.
  
  Create different hash tables for wildcarded conversations, to reduce the
  number of "is this a wildcard?" tests done when doing hash lookups.
  
  This is sufficient to allow the TFTP dissector to use conversations
  rather than being special-cased in the UDP dissector, and may also be
  sufficient to handle a similar problem with SMTP (request goes from
  client IP X port Y to server IP Z's well-known port, reply comes back
  from some other port on server Z to client IP X port Y), but further use
  may reveal other changes that should be made.
