Keep the "/ sizeof(uint32_t)" here, rather than folding it into RTE_THASH_MAX_L4_LEN.
At your preference, keep RTE_THASH_MAX_L4_LEN (removing "in dwords" from it comment) or simply use:
uint32_t tmp_tuple[sizeof(union rte_thash_tuple) / sizeof(uint32_t)];

With sizeof(uint32_t) back in tmp_tuple...
