You are simplifying quite a bit here, listing just these pages. When i
see figure 8-1, CMIS Module Memory Map, i see many more pages, and
banks of pages.
The current API is getting more and more strand to support SFP
EEPROMs. We really do need to think of a new API, and it seems like
now is a good time to do it, in order to support these devices.
