Why rte_has_hash() in DPDK-2.0 isn't multi thread safe?

It only calculates hash.


* Calc a hash value by key. This operation is not multi-process safe.
* @param h
*   Hash table to look in.
* @param key
*   Key to find.
* @return
*   - hash value

rte_hash_hash(const struct rte_hash *h, const void *key)
               /* calc hash result by key */
               return h->hash_func(key, h->key_len, h->hash_func_init_val);
