Before MC-aware mode was enabled in commit 7b81953066 ("mlxsw:
spectrum: Configure MC-aware mode on mlxsw ports"), only 8 traffic
classes were used. Under MC-aware regime, however, besides using TCs
0-7 for UC traffic, it additionally uses TCs 8-15 for BUM traffic. It
is therefore desirable to show counters for these TCs as well.
Update ethtool stats pool length, mlxsw_sp_port_get_strings() and
mlxsw_sp_port_get_stats() to include artifacts for all 16 TCs. For
consistency and simplicity, expose tc_no_buffer_discard_uc_tc for BUM
TCs as well, even though it ought to stay at 0 all the time.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
