Subject: Re: [dpdk-dev] Is rte_mempool library is multi-thread safe ???

does that mean that on the same core, we can't do rte_eth_rx_burst in one
thread (I assume this function allocates from mempool for storing mbufs
everytime it receives a packet), while another thread calls
rte_pktmbuf_alloc from the same mem_pool?
