Subject: Re: [dpdk-dev] ixgbevf: queue start stop functions
Hello,
I'm working on a procedure that will handle Ethernet link failure over ixgbe VF.
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 again after starting the devices. Please reference these 2 functions in testpmd, stop_packet_forwarding and start_packet_forwarding.
Thank you.
Regards,
Gregory
