DSFP is a new cable module type, which EEPROM uses memory layout
described in CMIS 4.0 document. Use corresponding standard value for
userspace ethtool to distinguish DSFP's layout from older standards.
Add DSFP module ID in accordance to SFF-8024.
DSFP module memory can be flat or paged, which is indicated by a
flat_mem bit. In first case, only page 00 is available, and in second -
multiple pages: 00h, 01h, 02h, 10h and 11h.
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.
Right, but as I understand these are the basic 5 pages which are
mandatory. Supporting more than that we will need new API.
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.
