ethtool: add standard FEC statistics
This set adds uAPI for reporting standard FEC statistics, and
implements it in a handful of drivers.
The statistics are taken from the IEEE standard, with one
extra seemingly popular but not standard statistics added.
The implementation is similar to that of the pause frame
statistics, user requests the stats by setting a bit
(ETHTOOL_FLAG_STATS) in the common ethtool header of
ETHTOOL_MSG_FEC_GET.
Since standard defines the statistics per lane what's
reported is both total and per-lane counters:
# ethtool -I --show-fec eth0
FEC parameters for eth0:
Configured FEC encodings: None
Active FEC encoding: None
Statistics:
corrected_blocks: 256
Lane 0: 255
Lane 1: 1
uncorrectable_blocks: 145
Lane 0: 128
Lane 1: 17

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.
