uint8_t* rss_key¶

In rte_eth_dev_rss_hash_conf_get(), the rss_key_len should be greater than or equal to the hash_key_size which get from rte_eth_dev_info_get() API. And the rss_key should contain at least hash_key_size bytes. If not meet these requirements, the query result is unreliable even if the operation returns success.

In rte_eth_dev_rss_hash_update() or rte_eth_dev_configure(), if rss_key is not NULL, the rss_key_len indicates the length of the rss_key in bytes and it should be equal to hash_key_size. If rss_key is NULL, drivers are free to use a random or a default key.
