When we set Rx offloads RSS hash off in cmdline, then we start port, if dev->data->dev_conf.rxmode.mq_mode RSS enable(multiple queues mode), it will load RSS hash in driver and sync to port.After setting Rx offloads RSS hash off, this patch removes RTE_ETH_MQ_RX_RSS in port->dev_conf.rxmode.mq_mode to fix this issue. And after setting Rx offloads RSS hash on, this patch also adds RTE_ETH_MQ_RX_RSS in port->dev_conf.rxmode.mq_mode.

I don't why you used immediate value, but you mean 'RTE_ETH_RX_OFFLOAD_RSS_HASH' here.

Why enabling RSS when 'RSS HASH' offload is enabled? In this case if RSS is disabled I think it should fail. Can you please describe again what problem you are solving?
