It means on the [tx]rx_queue_setup the application should set the port offloads also in the queue offloads. This is the API for the application, and there is an ongoing discussion to remove this limitation, see [1].

You may add a routine to verify that (on the queue setup), or ignore completely the queue offloads configuration .
