Receive Poll Demand
When these bits are written with any value, the DMA reads the current descriptor pointed to by Register GMAC_CUR_HOST_RX_DESC. If that descriptor is not available (owned by Host), reception returns to the Suspended state and Register GMAC_STATUS[7] is not asserted. If the descriptor is available, the
Receive DMA returns to active state.

This field contains the base address of the First Descriptor in the Receive Descriptor list. The LSB bits [1/2/3:0] for 32/64/128-bit bus width) will be ignored and taken as all-zero by the DMA internally. Hence these LSB bits are Read Only.
