Now that NAPI has been implemented, the hardware interrupt mitigation mechanism is not needed to avoid excessive interrupt load in most cases. Reduce the default RX interrupt threshold to 1 to reduce introduced latency. This can be increased with ethtool if desired if some applications still want to reduce interrupts.
