Patch 1 is an optimization that resets the DATA_READY bit when we re-enable Rx interrupts. This optimization lets us exit quickly from vnet_event_napi() when new data has not triggered an interrupt. Sowmini Varadhan (3): Correction to RFC number in comment Reset LDC_EVENT_DATA_READY when napi completes.
