  • set

[Waiting for support]

Suggestions for adding support:
  • Add counters to each element of a set. A counter contains the number of packets that matched an element and the total number of bytes. There must be the option of enabling or disabling the update of counters' values at will. Also counters' values must be accesible in order to do comparisons.
  • Sets must include different types of elements. Sets must have support for the "nomatch" flag.
