Hi Ferruh,
Thanks for this.. I had started working on a patch to do this as well
because I got bit by this error.
Shouldn't all of the example applications also add the code to strip
the unsupported Tx and Rx offload bits as well? It would help new
users (like me!) to understand that this is a requirement for all
callers of rte_eth_dev_configure().
rte_eth_dev_info_get(port_id, &dev_info);
/* Only set the offload bits which are actually supported */
port_conf.txmode.offloads &= dev_info.tx_offload_capa;
port_conf.rxmode.offloads &= dev_info.rx_offload_capa;
thanks
dan
