This gives the opportunity for more direct control of Tx interrupt handling, such as CPU affinity and interrupt coalescing, useful for some traffic loads. To enable, use the ethtool private flag: ethtool --set-priv-flag enp20s0 split-q-intr on To restore defaults ethtool --set-priv-flag enp20s0 split-q-intr off When enabled, the number of queues is cut in half in order to reuse the interrupts that have already been allocated to the device. When disabled, the queue count is restored.
