Currently all GRED's virtual queue data is dumped in a single array in a single attribute. This makes it pretty much impossible to add new fields. In order to expose more detailed stats add a new set of attributes. We can now expose the 64 bit value of bytesin and all the mark stats which were not part of the original design.
