net/i40e packet loss after Rx interrupt disable

Open-source test suite which has been run at UNH IOL has a number of test scenarios which check Rx interrupts support.
There is a common pattern of failures in 4 cases. If Rx interrupt is disabled, the next packet to be received is lost [1], [2], [3] and [4].
