+// EthernetInterface Modifications to enhance it slightly.
+//
+// This set of modifications integrates with the mbed standard EthernetInterface stack.
+// It does require one-line modifications of both EthernetInterface.h and EthernetInterface.cpp.
+//
+// CAUTION: This works with the LPC1768, but some of the interfaces may be unique to that part.
+//
+// Two steps integrate this:
+//
+// STEP 1: edit EthernetInterface.h as follows:
+//
+//      class EthernetInterface {
+//      public:
+//          ... normal EthernetInterface APIs
+//
+            // add this in the public section, at the bottom
+//          #include "EthernetInterface_Mods.h" 
+//      };
+//
+// STEP 2: edit EthernetInterface.cpp as follows:
+//
+//      // add this at the end of the file
+//      #include "EthernetInterface_Mods.hxx"
+//
+#ifndef ETHERNETINTERFACE_MODS_H
