/*
 * The following set of constants are from Document SFF-8472
 * "Diagnostic Monitoring Interface for Optical Transceivers" revision
 * 11.3 published by the SFF Committee on June 11, 2013
 *
 * The SFF standard defines two ranges of addresses, each 255 bytes
 * long for the storage of data and diagnostics on cables, such as
 * SFP+ optics and TwinAx cables.  The ranges are defined in the
 * following way:
 *
 * Base Address 0xa0 (Identification Data)
 * 0-95    Serial ID Defined by SFP MSA
 * 96-127  Vendor Specific Data
 * 128-255 Reserved
 *
 * Base Address 0xa2 (Diagnostic Data)
 * 0-55    Alarm and Warning Thresholds
 * 56-95   Cal Constants
 * 96-119  Real Time Diagnostic Interface
 * 120-127 Vendor Specific
 * 128-247 User Writable EEPROM
 * 248-255 Vendor Specific
 *
 * Note that not all addresses are supported.  Where support is
 * optional this is noted and instructions for checking for the
 * support are supplied.
 *
 * All these values are read across an I2C (i squared C) bus.  Any
 * device wishing to read these addresses must first have support for
 * i2c calls.  The Chelsio T4/T5 driver (dev/cxgbe) is one such
 * driver.
