Hi Chandrika are you using the i40e-zc driver or the standard driver? Please note that ZC enables interrupts only when required for performance reason, for example some libpcap-based applications require interrupts as they use poll/select, instead many pf_ring-based application do not use interrupts at all (they do active polling).
