Try blacklisting (-b 0000:01:00.1 -b ...) all of the ports you are not using. The number of ports being setup is taken from the number of devices DPDK detects. The only on thing I am worried about is the ' max_rx_queues : 0, max_tx_queues : 0’ is reporting zero queues. It maybe other example code does not test the return code from the rte_eth_dev_configure() call. I think the max_rx_queues and max_tx_queues should be at least 1. > > Thanks, > > Philip Lee Regards, Keith
