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.
