You can look for "seq++" or similar in the code and then comment out
that line.
However, keep in mind that Interests with the same sequence numbers may
be aggregated/dropped in the PIT, and you might run into other problems.

You can get the queue size in bytes/packets from a pointToPointNetDevice:

> uint32_t nBytes = queue->GetNBytes();
