   15   The Ring Accelerator (RA) is a machine which converts read/write accesses
   16   from/to a constant address into corresponding read/write accesses from/to a
   17   circular data structure in memory. The RA eliminates the need for each DMA
   18   controller which needs to access ring elements from having to know the current
   19   state of the ring (base address, current offset). The DMA controller
   20   performs a read or write access to a specific address range (which maps to the
   21   source interface on the RA) and the RA replaces the address for the transaction
   22   with a new address which corresponds to the head or tail element of the ring
   23   (head for reads, tail for writes).
   24 
   25   The Ring Accelerator is a hardware module that is responsible for accelerating
   26   management of the packet queues. The K3 SoCs can have more than one RA instances
