The DPDK is compiled into the snort DAQ lib statically. The DAQ lib is = then linked to snort statically. What I am find is that the rte_mempool_ops_table is all 0, causing the clie= nt to crash when free the received mbuf from the ring. I was wondering how = this rte_mempool_ops_table is populated during DPDK initialization for a cl= ient application. The my dpdk snort went through rte_eal_init(), rte_ring_lookup() and rte_me= mpool_lookup() without error. Thanks Ming
