As per the current suggested code flow check is added to while loop in function `dump_packets'. 

Questions:
1. What is impact in performance with and without patch?
2. For various packet sizes and port speed what are delta in drops for packet capture?

Note: If pdump application is still alive when primary is not running, primary cannot be started. Is this a cue that pdump is still alive and has to be terminated?
