The next list descriptor address registers, shown in
the next list descriptor in memory. If the contents are transferred to the current list descriptor address
register they become effective for the current transfer in extended chaining mode.

16.3.1.12
The source stride register, shown in
stride information is loaded when a new list descriptor is read from memory. Therefore, the source stride
register is applicable for all link descriptors in the new list. Changing the source stride information for a
link requires that a new list be generated.
