* This is used for QPLL reset when several core are present

* Add the possibility to specify which GTH is used.
* It is possible to instanciate up to 4 CCN. This is still dumbly coded.
  I did not find a clean solution.
* Reducing the name to CCN for ComCellNode

* Changing name of component
* The used transceivers is declared in $Config(GTH_LOC)
* Still some hard coded values for DAMC FMC2ZUP

Should be set by project script.

* Also change the package version name and import it

* Add version register.
* Add registers decription.
* Ad a small documentation.

* RX/TX swap on clock active (two drivers)

* This module now only contains 10GbE configured for comcellnode.
* Also bring correction for synthesis

* Ethernet core is now 'comcellnode_ethernet_core'.
* Drop all capitals letters in addrespace name.

* Not tested

* Move integration of ethernet IP to comcellnode_ethernet.
* New top level file that integrate ethernet and packeter.
* Need AXI-MM logic.

* Not synthesized yet
* Well tested, need to automate and do special cases

* Tested via simulation
* still no header insertion

* OK for one sequence
* No timeout yet
* No new features

* Only Sequence detector and frame counter
* No header insertion yet
* Not simulated, not synthesized

* Change the External data path on GT wizard settings
* tie the loopback to top level
* bring the usrclk2 out to the top level
