+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.
