For different qualifiers and actions, there are different data lengths. For example, an IP address
is 32 bits long, a MAC address is 48 bits long, and an L4 port ID is 16 bits long. This data
structure was defined in order to accommodate these different situations. Careful attention must
be paid to refer to the appropriate member according to the actual situation. The appropriate
members for existing qualifiers and actions are listed in the Tables 6-3 and 6-4.
