This series enables multi-queue and control vq features
for ifcvf.

These patches are based on my previous vDPA/ifcvf management link
implementation series:

Thanks!

Patch looks good.

I wonder the compatibility. E.g does it work on the qemu master
without cvq support? (mq=off or not specified)

Hi Jason,

Yes, it works with qemu master. When no cvq/mq support, only one queue
pair shown.

Good to know this.

Thanks

Thanks,
