net: sched: gred: provide a better structured dump and expose stats
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.
