/*
* This routine creates one entry in the list of protocol dissector

*
* @param table_name The table name in which this dissector is found.
*
* @param key A pointer to the key for this entry in the dissector
* hash table. This is generally the numeric selector of the
* protocol, i.e. the ethernet type code, IP port number, TCP port
* number, etc.
*
* @param value A pointer to the value for this entry in the dissector
* hash table. This is an opaque pointer that can only be handed back
* to routine in the file packet.c
*
* @param user_data A pointer to the list in which this information
* should be stored.
