+              The tx_lso_enable property controls whether or not the device
+              enables support for Large Segment Offloand (LSO) when
+              transmitting packets.  The default is to always enable support
+              for this.  Turning it off will decrease throughput when
+              transmitting packets, but should be done if a hardware bug is
+              suspected.
