* Description: Configuration parameters for receive DMA block.
* Fields in this register are part of the dma configuration and

* The usage of enable, reset, and qst is as follows. Software
* should use the following sequence to reset a DMA channel. First,
* set DMA.enable to 0, wait for DMA.qst=1 and then, set DMA.reset to
* 1. After DMA.reset is cleared by hardware and the DMA.qst is set
* to 1, software may then start configuring the DMA channel. The
* DMA.enable can be set or cleared while the DMA is in operation.
* The state machines of the DMA may not have returned to its initial
* states yet after the DMA.enable bit is cleared. This condition is
* indicated by the value of the DMA.qst. An example of DMA.enable
* being cleared during operation is when a fatal error occurs.
* Fields:
* Set to 1 to enable the Receive DMA. If set to 0, packets
* selecting this DMA will be discarded. On fatal errors, this
* bit will be cleared by hardware. This bit cannot be set if sw
* has not resolved any pending fatal error condition: i.e. any
* RdcStat ldf1 error bits remain set.
* Set to 1 to reset the DMA. Hardware will clear this bit after
* reset is completed. A reset will bring the sepecific DMA back
* to the power on state (including the DMA.en in this register).
* When set to 1, it indicates all state associated with the DMA
* are in its initial state following either dma reset or
* disable. Thus, once this is set to 1, sw could start to
* configure the DMA if needed.
* Bits [43:32] of the Mailbox address.
