hi, I recently using dpdk primary as a stable program that won't exit maybe for a month, so i need do rx_burst in a secondary program,however, cause the secondary does a lot work and it may exit at any time,and restart, here is my question:
1.how to smoothly free or reset the ring,mempoop,zone and rte_ip_frag_tbl
before my secondary process start up at next time?
2.what can i do to prevent memery leaking as my secondary process would
restart many times?

very much looking forword your reply.
