Handle extended compliance code 0x1 (SFF8024_ECC_100G_25GAUI_C2M_AOC) for active optical cables supporting 25G and 100G speeds. Since the specification makes no statement about transmitter range, and as the specific sfp module that had been tested features only 2m fiber - short-range (SR) modes are selected. The 100G speed is irrelevant because it would require multiple fibers / multiple SFP28 modules combined under one netdev. sfp-bus.c only handles a single module per netdev, so only 25Gbps modes are selected. sfp_parse_support already handles SFF8024_ECC_100GBASE_SR4_25GBASE_SR with compatible properties, however that entry is a contradiction in itself since with SFP(28) 100GBASE_SR4 is impossible - that would likely be a mode for qsfp modules only. Add a case for SFF8024_ECC_100G_25GAUI_C2M_AOC selecting 25gbase-r interface mode and 25000baseSR link mode. Also enforce SFP28 bitrate limits on the values read from sfp eeprom as requested by Russell King. Tested with fs.com S28-AO02 AOC SFP28 module.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
