Buffer Descriptor List Pointer Lower Base Address — R/W. This field provides the
lower address of the Buffer Descriptor List. This value should only be modified when the
RUN bit is 0, or DMA transfer may be corrupted.
Hardwired to 0 forcing alignment on 128-B boundaries.
Buffer Descriptor List Pointer Upper Base Address — R/W. This field provides the
upper 32-bit address of the Buffer Descriptor List. This value should only be modified
when the RUN bit is 0, or DMA transfer may be corrupted.
