Subject: [dpdk-dev] [PATCH] test/mempool: Fix illegal pointer access in mempool
test
The value of parameter private_data_size of function
rte_mempool_create() called in test_mempool() should not be 0, Otherwise, the
function rte_pktmbuf_priv_size() called in
rte_pktmbuf_init() will cause heap-buffer-overflow.
