At this time, ``rte_eth_rx_queue_setup`` api is\n+needed to reroute rxq to the RX path with offload function. But at this\n+time, it is possible that the original Rx path is handling packages, so\n+this is not thread-safe.\n+\n+When applying offload on the PF or DCF, starting the ``testpmd``\n+application, use the ``--rx-offloads`` startup parameter to force the\n+dpdk lib to choose the Rx path with the offload function by default.\n+\n", "prefixes": [ "v7" ] }
