>> the output is:
>> PKT 12201
>> PKT 12202
>> PKT 12203
>> PKT 12204
>> PKT 12205
>> PKT 12206
>> PKT 12202
>> PKT 12208
>>
>> total received pkts is identical to the total delivered pkts, but part of
>> the pkts are being received twice...

Enabling CONFIG_RTE_LIBRTE_MEMPOOL_DEBUG and
CONFIG_RTE_LIBRTE_MBUF_DEBUG could help you to track
double free or corruptions.
