[dpdk-dev] Dpdk version 17.11.4 (i40e) switchover is not working

[chetan bhasin]

Hello folks,

I am using dpdk 17.11.4 version , it's a bare metal server with intel X722
nic with firm-ware version 4.0.

The problem is switch-over is not working, looks like dpdk is not able to
get link down trigger.

Can anybody guide us please .

Thanks,
Chetan Bhasin

Hello Everyone,

I have figured out the DPDK version , i.e 18.11.2 , where LSC is working
fine for i40e (X722) under bond setup.

So command-line I am using is
./testpmd  -c f -n 4  --vdev
'net_bonding0,mode=1,slave=0000:009:00.2,slave=0000:009:00.0,primary=0000:009:00.2'
-- -I

Can anybody please provide a direction towards which patch I should look
into , as there are lots of changes between dpdk-17.11.4 and dpdk-18.11.2.
I have tried some patches related to i40e driver but no success yet.

Thanks & Regards,
Chetan Bhasin

Would "git bisect" not work in this case to isolate the relevant patches?
