[dpdk-dev] ixgbevf: queue start stop functions

[dpdk-dev] ixgbevf: queue start stop functions

[Gregory Etelson]

Hello,

ixgbevf PMD has no implementation for RX/TX queue start/stop functions in DPDK-17.05.0
Is there a roadmap to add these functions to DPDK ?

Thank you
Regards,
Gregory

I'm afraid there's no plan to support it because lack of interface between PF and VF :(

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 ?

Thank you.

Regards,
Gregory

[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.

Gregory
