net/i40e does not report interrupt=
 for the second packet

If I understand Rx interrupts functionality correctly, Rx interrupts should=
 be
generated until disabled. However, it does not happen in the case of i40e w=
ith
X710 NIC.

The problem is found by open-source test suite which has been run at UNH IOL
[1].

Scenario is simple:
 - enable Rx interrupts
 - send packet from peer
 - check interrupt, receive packet
 - send one more packet
 - check interrupt - failure, no interupt
