Subject: RE: [PATCH net-next V3 0/9] liquidio CN23XX VF support

Hi Dave,

Regarding module parameters num_queues_per_{p,v}f, in non-default case if user wants to have multiple queues then because of the way Liquidio HW works we need num_queues_per_pf and num_queues_per_vf module parameters at HW/module init time. This is because in multi-queues per VF scenario, HW has to carve these queues before FW can start communicating with PF/VF host drivers. So we must include these two parameters incase more than queue is needed by VF.

I did not get reply from you when I requested you for confirmation couple of weeks back about the same two module parameters as shown in the mail attachment. 

So please confirm if you want us to remove these two parameters num_queues_per_{p,v}f. Then I can remove these module parameters and resubmit the patches. 

Thanks and Regards
Raghu.
