void Table::Actions::add_action_format	(	const Table *	table,
		json::map &	tbl ) const

This following few fields are required on a per stage table action basis. The following information is:

• next_table - The value that will be written into the next field RAM line on a hit, when the entry is specified with this action. This is either an index into the next_table_map_en (if that map is enabled), or the 8 bit next table value.
• next_table_full - The value that will be written into the miss register for next table (next_table_format_data.match_next_table_adr_miss_value), if this action is set as the default action. This is the full 8 bit (9 bit for JBay) next table.
• vliw_instruction - The value that will be written into the action instruction RAM entry when the entry is specified with this action. This is either an index into into the 8 entry table mau_action_instruction_adr_map_data, if that is enabled, or the full word instruction
• vliw_instruction_full - The value that will written into the miss register for action_instruction (mau_action_instruction_adr_miss_value), when this action is specified as the default action. The full address with the PFE bit enabled.
