Without queues reset functionality I tried to reset DPDK port with rte_eth_dev_stop();rte_eth_dev_start() sequence. My tests show that call to dev_stop can hang a process. Can you suggest another procedure for VF port reset on link down ? [Wenzhuo] APP need stop rx/tx before stopping the devices and start rx/tx a= gain after starting the devices. Please reference these 2 functions in test= pmd, stop_packet_forwarding and start_packet_forwarding. Thank you.
