Jason Wang 3df97ba830 tuntap: calculate rps hash only when needed ... There's no need to calculate rps hash if it was not enabled. So this patch export rps_needed and check it before trying to get rps hash. Tests (using pktgen to inject packets to guest) shows this can improve pps about 13% (when rps is disabled). Before: ~1150000 pps After: ~1300000 pps Cc: Michael S.
