[dpdk-dev] [PATCH v2] app/testpmd: fix set Rx offloads RSS hash off

[Jie Wang]

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.

Fixes: c73a9071877a ("app/testpmd: add commands to test new offload API")
