This application uses two eth interfaces and creates two KNI interfaces to
forward the packets:
- the encapsulated ones through the eth interfaces

The problem I'm facing is my mbuf free count (as given by

application stops forwarding.
Any clues about what I could do to liberate the free mbufs back to the
