- Set default RX coal packets to 64, so RX coal timeout takes control during   bulk data operations.  This greately reduces the interrupt rate while keeps   bulk data performance. - Set default TX coal packets to 64 and TX coal timeout to 65535us (maximum   allowable value).  This greately reduce the interrupt rate while greately   increases (almost doubles) small packet TX performance.
