+= COMCELLNODE ETHERNET module documentation
+
+// ================================================================================
+== Description
+This module instantiate the Xilinx Ethernet Subsystem for 10 GbE communication.
+
+The GT wizard core is separated from the Ethernet Subsystem, to allow different transceivers form one quad to run different communication type (ie Gbe and COMBPM).
+
+
+// ================================================================================
+== Overview
+
+=== Main operation: Top level
+
+This module is mainly structural, connecting the IP blocks with the control and status of the AXI-MM interface.
+
+The QPLL core shall be instanciated by the application, providing a 156.25 MHz clock ref.
