Hi Simon,

Thanks very much for your advice.


V3===>V4:
1. Modify the parameter from '-m/--more' to '--offload-stats'.
2. Rename the structure from 'pkts_stats' to 'pkt_stats'.
3. Change the position of some code comments.
4. Rename from 'verbosity' to 'offload_stats'.
5. Some modifications based on the rest of your advice.
