Description

Currently, the IP classifiers simply assume that all IP packets do not have IP options. If an IP packet has IP options, the current behavior is undefined (e.g., might be redirected/mirrored to a random link).

We can solve that by adding one more rule to the filter requiring the length of the IP packet to be 5 bytes.
