How did you find out your packets are too big? It might hangs some where processing the packets, i.e. in the driver.

These kind of questions have no specific answers; they are looking for your detective skills.

I would not assume the test case hangs because of very large packet unless someone already has knowledge about why that causes a hang. You need to ask why; otherwise it may just be a coincidence.

How do you know the test case hangs? It could be just very slow.
