Packet Mark is an analogue to ipfw tags with O(1) lookup from mbuf while regular tags require a single-linked list traversal. Mark is a 32-bit number that can be looked up in a table [with 'number' table-type], matched or compared with a number with optional mask applied before comparison. Having generic nature, Mark can be used in a variety of needs. For example, it could be used as a security group: mark will hold a security group id and represent a group of packet flows that shares same access control policy.
