            Bug ID: 1073
           Summary: The `rte_mempool_ops_table` is process unsafe

GDB print value corresponding to the table（rte_mempool_ops_table）（myapp and dpdk-pdump）

The rte_mempool_ops_table is process unsafe!

When a process is started, the table (rte_mempool_ops_table) will be initialized with a macro (rte_mempool.h:MEMPOOL_REGISTER_OPS). However, different process initialization will cause inconsistent index values (ops_index) (such as myapp and dpdk pdump). After the initialization memory pool is created in the dpdk pdump process, mp->ops_index = 0, mp->ops_index=2 in myapp。 Different processes using the shared memory pool will be coredump
