> 
> v2 changes:
>   - turn on intr only when rxq flag is set
>   - rework base on patch http://dpdk.org/dev/patchwork/patch/7504/
> 
> The patch enables rx interrupt support on i40e VF and some necessary change on
> PF IOV mode to support VF.
> On PF side, running in IOV mode via uio won't allow rx interrupt which is exclusive
> with mbox interrupt in single vector competition.
> On VF side, one single vector is shared for all the rx queues.
