XFP I2C management interface structure decoder.
XFP modules include an I2C interface, used to monitor and control various
aspects of the module. The specification defines an I2C slave at address
0x50 (0xa0) which returns 128 bytes of a standard structure ("lower memory"),
and, after setting a table number in lower memory, a set of 256 "higher
memory" tables, which can be mapped to different subdevices on the XFP.
Only one table is defined in the specification: table 0x01, the default on
module startup. Other table are either reserved for future expansion, or
available for vendor-specific extensions. This decoder supports both lower
memory and table 0x01.
The XFP specification is available here:
