Tobias Waldekranz says: ==================== net: dsa: mv88e6xxx: Add "eth-mac" and "rmon" counter group support The majority of the changes (2/8) are about refactoring the existing ethtool statistics support to make it possible to read individual counters, rather than the whole set. 4/8 tries to collect all information about a stat in a single place using a mapper macro, which is then used to generate the original list of stats, along with a matching enum. checkpatch is less than amused with this construct, but prior art exists (__BPF_FUNC_MAPPER in include/uapi/linux/bpf.h, for example). To support the histogram counters from the "rmon" group, we have to change mv88e6xxx's configuration of them. Instead of counting rx and tx, we restrict them to rx-only. 6/8 has the details. With that in place, adding the actual counter groups is pretty straight forward (5,7/8). Tie it all together with a selftest (8/8). v3 -> v4: - Return size_t from mv88e6xxx_stats_get_stats - Spelling errors in commit message of 6/8 - Improve selftest: - Report progress per-bucket - Test both ports in the pair - Increase MTU, if required v2 -> v3: - Added 6/8 - Added 8/8 v1 -> v2: - Added 1/6 - Added 3/6 - Changed prototype of stats operation to reflect the fact that the number of read stats are returned, no errors - Moved comma into MV88E6XXX_HW_STAT_MAPPER definition - Avoid the construction of mapping table iteration which relied on struct layouts outside of mv88e6xxx's control ==================== Signed-off-by: David S.

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.
