Buffer Descriptor List Pointer Lower Base Address — R/W. This field is 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 is 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.
