Hi Alfredo, Interrupts are not seen either with standard driver or with the zc compiled i40e driver as well.
What we do in our application is - We load zc compiled i40e driver and put a zc license on that interface but we do not open device using zc: prefix. Using this we have observed better performAnce in our application when used with ixgbe driver.
