How about change it following format?

"-T PERIOD: statistics will be shown every PERIOD seconds (only if interactive is

Add line after printf("  --help: ......
printf("-T PERIOD: statistics will be shown every PERIOD seconds (only if interactive is disabled)\n");

Spotted a CamelCase ;)
Is there a punishment planned in the contributor's guide?

Considering all the option are in small letter, Does it makes sense to
make it as small letter? (ie -t instead of -T).

Other than it looks good and useful feature.

Thank you for the update.
Please, may I request a v5 rebased on current master?

Oh... sure, sorry about that. Will send a v5, and probably change the parameter name,
as per Jerin's request.

Thanks for the testing. I took the parameter name from L2fwd, but you are right,
it should be lowercase. Actually, to make it more explicit, I propose 
to change it to "--stats-period".

Will send a v5 soon.
Thanks,
Pablo
