30  * The following set of constants are from Document SFF-8472
31  * "Diagnostic Monitoring Interface for Optical Transceivers" revision
32  * 11.3 published by the SFF Committee on June 11, 2013
33  *
34  * The SFF standard defines two ranges of addresses, each 255 bytes
35  * long for the storage of data and diagnostics on cables, such as
36  * SFP+ optics and TwinAx cables.  The ranges are defined in the
37  * following way:
38  *
39  * Base Address 0xa0 (Identification Data)
40  * 0-95    Serial ID Defined by SFP MSA
41  * 96-127  Vendor Specific Data
42  * 128-255 Reserved
43  *
44  * Base Address 0xa2 (Diagnostic Data)
45  * 0-55    Alarm and Warning Thresholds
46  * 56-95   Cal Constants
47  * 96-119  Real Time Diagnostic Interface
48  * 120-127 Vendor Specific
49  * 128-247 User Writable EEPROM
50  * 248-255 Vendor Specific
51  *
52  * Note that not all addresses are supported.  Where support is
53  * optional this is noted and instructions for checking for the
54  * support are supplied.
55  *
56  * All these values are read across an I2C (i squared C) bus.  Any
57  * device wishing to read these addresses must first have support for
58  * i2c calls.  The Chelsio T4/T5 driver (dev/cxgbe) is one such
59  * driver.
