In it, an entry key is a set of exact match fields: an EtherType, a pair of IP addresses, a L4 protocol ID and a pair of L4 port numbers. An entry response can provide matching packets with a mark value and additional data to be plumbed to NAT action. In addition, an update to mark-and-sweep counter can be done. This table was designed with larger capacity in mind, so moving the above match criteria out of an action rule (AR) specification to a CT entry increases the likelihood of reusing AR entries and improves the total flow engine capacity. Make use of that.
