What does that mean? Need more here. I don't know how the translation hardware works, but is there a fundamental page size or something like that, or does it need to be on a *size* aligned boundary? Please specify that in the interfaces. What if that mapping is already valid? Does it simply replace the previously valid mapping, or does the interface require that that entry be unused at the time the new mapping is set up? Does the 'unmap' imply any sort of flush? > 2. niu_rx_logical_page_get What's the return value if that chidx/pgidx pair is an unmapped "page"? size 0? Please specify and I think you want to specify that raddr is ignored when size is 0, and the implementation should put 0 in there instead of whatever happens to be in that register if the mapping is invalid. And the same questions for the other 2 interfaces.

For niu_rx_logical_page_get and niu_tx_logical_page_get, if there is no current mapping, 0 is returned for both real address and size. For niu_rx_logical_page_set and niu_tx_logical_page_set, the mapping is invalidated if the size is 0. We can make explicit that 'raddr' ignored in this case.
