In it,\nan entry key is a set of exact match fields: an EtherType, a\npair of IP addresses, a L4 protocol ID and a pair of L4 port\nnumbers. An entry response can provide matching packets with\na mark value and additional data to be plumbed to NAT action.\nIn addition, an update to mark-and-sweep counter can be done.\n\nThis table was designed with larger capacity in mind,\nso moving the above match criteria out of an action\nrule (AR) specification to a CT entry increases the\nlikelihood of reusing AR entries and improves the\ntotal flow engine capacity.
