As a nit this line and similar line above can be merged into one and put
before 'if' statement above, i.e.:

vec[0].base = rte_pktmbuf_mtod_offset(mb, void *, ofs);
vec[0].iova = rte_pktmbuf_iova_offset(mb, ofs);
vec[0].tot_len = mb->buf_len - rte_pktmbuf_headroom(mb) - ofs;

Same as above - these two lines can be put as one before 'if'.
