 The filter implements an optimization for matching SFF frames using a bitmap
 with one bit for every ID. With this optimization, the classification time
 for SFF frames is nearly constant independently of the number of rules.

 The decision whether to use the bitmap- or array-based implementation needs
 to be done at compile time.
