+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:
+
+ ftp://ftp.seagate.com/sff/INF-8077.PDF
