During 1.3 we completed the discussion that any new config field addition must adhere to DMA interface and not a register.
Multiple capabilities need this.
So lets please work on that.

Counters needs to use the dma interface and it can wait one time to utilize the modern interface.

I have two proposals to for the dma interface and we should discuss that in separate thread to not mix the cvq parts of the stats.
I will start the thread shortly and put pointer to this requirement of counters + many others that we are discussing including ntuple.
