> Are all these explicit type casts really needed? buf_iova is already uint64_t, buflen is uint16_t, data_off is uint16_t, rte_mbuf_refcnt_read() returns uint16_t, pkt_len is uint32_t, nb_segs is uint16_t, port is uint16_t, vlan_tci is uint16_t.

Normally, they are not needed.
If you turn up some of the warning levels in Gcc, then yes.

Makes sense, but since this in internal would rather keep existing
 to print the name of the field.

good idea, personal preference is to always use %#x over %x
