erj 87656821dc ifconfig(8): Display extended compliance code string for SFP transceivers
- Updates tables in affected files with new entries from newer spec
revisions of SFF-8472, SFF-8024, and SFF-8636

- Change ifconfig to read and display the extended compliance code for
SFP media if the extended compliance code is not 0. This was being displayed
for QSFP transceivers only, but SFP28 media uses this to report 25G
capability.

* 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.
