[ndnSIM] Obtaining the number of Interest packets

Yes, I found 88 Data responses for Interest1 and 48 Data responses for
Interest2.
I thought that regardless of the frequency rate, if the number of generated
Interests reached the specified number of contents, no more Interests will
be generated. It's not the case?

My best regards,
Zakaria
