An entry in the filterStatement table. Each entry represents one of a sequence of statements that comprise a filter. Each filter statement consists of an index, specific packet header fields, and arbitrary packet offsets and values. Some objects in this entry define ranges for specific packet header fields. These objects define comparison operations on the field they share in the following manner: Low High Compare Method for field f 0 0 no comparison on the field 0 H less than or equal to High (f <= H) L 0 exact match (L == f) L H inclusive between comparison (L <= f <= H)
