    /projects/lagopus/src/dpdk/build/include/rte_mbuf.h:
    In function 'rte_pktmbuf_detach':
    /projects/lagopus/src/dpdk/build/include/rte_mbuf.h:
    1583:17: warning: conversion from 'uint32_t' {aka
    'unsigned int'} to 'uint16_t' {aka
    'short unsigned int'} may change value [-Wconversion]
      m->priv_size = priv_size;
                     ^~~~~~~~~

    The temp priv_size is declared as a uint32_t.  But it
    only deals in uint16_t.  m->priv_size is a uint16_t.
    Change it to a uint16_t.
