While talking with Kevin, he pointed out the error in this code. We are updating queue level offloads, with whatever in the 'offloads' and it can be non-queue level offloads in it, next time ethdev API called these values are caught by the API checks and causing an error. It looks like port level offload flags needs to be masted out before writing to queue level 'offloads' variable. > > /* Check if any Rx parameters have been passed */ > if (rx_pthresh != RTE_PMD_PARAM_UNSET) > @@ -2833,7 +2836,9 @@ rxtx_port_config(struct rte_port *port) > } > > for (qid = 0; qid < nb_txq; qid++) { > + offloads = port->tx_conf[qid].offloads; > port->tx_conf[qid] = port->dev_info.default_txconf; > + port->tx_conf[qid].offloads |= offloads; > > /* Check if any Tx parameters have been passed */ > if (tx_pthresh != RTE_PMD_PARAM_UNSET) >
