## Table of (Node, Protocol) pairs
This table describes the protocol to be expected at b->data[b->current_data] upon entry to the dispatch function. The intended use of these data is to teach our dispatch trace wireshark dissector to properly decode the next protocol. If the node name isn't know to the dissector, it looks at b->data[b->current_data]. If the answer is 0x45 or 0x60, the dissector guesses ipv4 or ipv6, respectively. Otherwise, the dissector guesses ethernet mac.

Once this table is reasonably complete, we'll turn the data into a set of heuristic overrides.
