RPDTB[31:0]:
The receive packet descriptor table base bits (RPDTB[31:0]) provides the
base address of the Receive Packet Descriptor Table in PCI host memory.
This register is initialised by the host. To calculate the physical address of a
RPD, the 15 bit RPD offset must be added to bits 31 to 4 of the Receive
Packet Descriptor Table Base (RPDTB[31:4]).
The table must be on a 16 byte boundary and thus the least significant four
bits must be written to logic zero.
