GCC 8.1 warned:
In function 'rte_pktmbuf_linearize':
rte_mbuf.h:1873:32: warning: conversion to 'int' from 'uint32_t'
{aka 'unsigned int'} may change the sign of the result [-Wsign-conversion]
rte_mbuf.h:2166:13: note: in expansion of macro 'rte_pktmbuf_pkt_len'
copy_len = rte_pktmbuf_pkt_len(mbuf) - rte_pktmbuf_data_len(mbuf);

rte_memcpy(buffer, rte_pktmbuf_mtod(m, char *), seg_len);
^~~~~~~
The temp is consumed as a size_t. So let's make it
a size_t in the first place.
