From: chunmei <chunmei....@intel.com>
ceph async messenger has some run time error with this dpdk library,
1) need set rxm->next= null at end of packet since not init it to null
when allocate a buffer other wise rte_mbuf_sanity_check will report error.
2) when check the size, can't calculate mbuf_data_room_size
because async messenger dpdk will allocate this part later
not at create mempool.
