- 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.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Add constants for use in interrogating various fiber and copper connectors
most often used with network interfaces.

The SFF-8472 standard defines the information that can be retrieved
from an optic or a copper cable plugged into a NIC, most often
referred to as SFP+. Examples of values that can be read
include the cable vendor's name, part number, date of manufacture
as well as running data such as temperature, voltage and tx
and rx power.

Copious comments on how to use these values with an I2C interface
are given in the header file itself.
