32 bit arch optimization suggestion

I was wondering... How widely is DPDK used with 32 bit architectures? Both phys_addr_t and rte_iova_t are cast as uint64_t in rte_common.h. Should they be uint32_t on 32 bit arch? If so, the rte_mbuf structure has 12 unused byte in the first cache line on 32 bit arch. Now, moving the "next" (
