LAST_VALID_INDEX:
The value written to this register indicates the index for the last
valid Buffer Descriptor in the BDL. After the controller has processed this descriptor it
will wrap back to the first descriptor in the list and continue processing. LVI must be at
least 1 i.e. there must be at least two valid entries in the buffer descriptor list before
DMA operations can begin. This value should only be modified when the RUN bit is 0
