And in the No.3 step, calling rte_eth_dev_configure API function, the internal function named hns3_dev_rss_hash_update check hw->rss_dis_flag is true and return -EINVAL. When user calls the rte_eth_dev_configure API function with the input parameter dev_conf->rxmode.mq_mode having ETH_MQ_RX_RSS_FLAG to enable RSS, driver should set internal flag hw->rss_dis_flag with false to indicate RSS is enabled in the '.dev_configure' ops implementation function named hns3_dev_configure and hns3vf_dev_configure.
