Add support for ethtool standard device statistics grouping. Support rmon
statistics grouping using rmon groups parameter in ethtool command. rmon
provides packet size based range grouping. Common mib parameters are used
across all KSZ series swtches for packet size statistics, except for
KSZ8830. KSZ series have mib counters for packets with size:
- less than 64 Bytes,
- 65 to 127 Bytes,
- 128 to 255 Bytes,
- 256 to 511 Bytes,
- 512 to 1023 Bytes,
- 1024 to 1522 Bytes,
- 1523 to 2000 Bytes and
- More than 2001 Bytes
KSZ8830 have mib counters upto 1024-1522 range only. Since no other change,
common range used across all KSZ series, but used upto only upto 1024-1522
for KSZ8830.

Weird linewrap. Please align the following lines with the opening brace
of the first one, e.g.
dev->dev_ops->r_mib_pkt(dev, port,
KSZ8_RX_64_OR_LESS + i, NULL,
cnt);
BUT I don't see why you need those braces around `macro + i` and without
them you can fit it into the previous line I believe.

This variable is getting updated on every call back after reading from
registers, so we cannot have it as constant.

Why are all commit messages indented in this way? Please keep the
default text indentation at 0 characters. I have never seen this style
in "git log".

Documentation/process/submitting-patches.rst:
Co-developed-by: states that the patch was co-created by multiple developers;
it is used to give attribution to co-authors (in addition to the author
attributed by the From: tag) when several people work on a single patch. Since
Co-developed-by: denotes authorship, every Co-developed-by: must be immediately
followed by a Signed-off-by: of the associated co-author. Standard sign-off
procedure applies, i.e. the ordering of Signed-off-by: tags should reflect the
chronological history of the patch insofar as possible, regardless of whether
the author is attributed via From: or Co-developed-by:. Notably, the last
Signed-off-by: must always be that of the developer submitting the patch.

I can make a guess
git show HEAD
notice how the commit message is indented. So if you where to
cut/paste that, you get the extra indent. It is better to do:
git commit -C 8e757b50555f3ae ; git commit --am
to copy a commit message from 8e757b50555f3ae, and then edit it to
suite.

Add support for ethtool standard device statistics grouping. Support
ethernet mac ctrl statistics grouping using eth-ctrl groups parameter
in ethtool command.

These should be reported as standard pause stats as well (ethtool -I --show-pause swpN).

Yes, these are reported as standards stats through get_pause_stats call
back.

because it's kool
Somebody not that long ago suggested that pre-increment is "less resource consuming":

Haha, classics.
It's not so common for people to show up back in the thread after you
ask them to show godbolt / asm code comparison.

idk what godbolt is, but if it's some sort of online compiler, then I
suppose it's of limited usefulness for the Linux kernel.
Easiest way to see a disassembly (also has C code interleaved) would be
this:
make drivers/net/dsa/microchip/ksz_ethtool.lst
This is also useful to see precisely which instruction went boom in case
there's a NULL pointer dereference or something like that.

Yeah it's an online compiler, which can spit out assembly code. For
testing non-complex stuff or macros it's often enough.

Oh, nice! I didn't know Kbuild has capability of listing the assembly

You can also do
make drivers/net/dsa/microchip/ksz_ethtool.o
make drivers/net/dsa/microchip/ksz_ethtool.S
etc to get any of the intermediary files from the build process.
Also
make drivers/net/dsa/microchip/
will build everything in that subdirectory and below. That can be much
faster, especially when you have an allmodconf configuration and it
needs to check 1000s of modules before getting around to building the
one module you just changed. FYI: the trailing / is important.

I was aware of this and .o, but didn't know about .lst and .S, hehe.
Yeah, this helps a lot. Sometimes I do
make W=1 <folder/file to recheck>
so that if a driver builds cleanly before my changes, it should do so
after them as well. `make W=1` for the whole kernel is still noisy
currently.

ethernet phy statistics grouping using eth-phy groups parameter in
ethtool command.

it is unused now.

now=since when?

Yes, this variable is never used after declaration, will update commit
message accordingly

I'd like to see the cover letter's subject prefixed as well, e.g.
[PATCH v2 net-next 0/5] net: dsa: microchip: add ethtool categorized
statistics
...or so, depending on the usual prefix for ksz.
Otherwise, it looks like you're adding something generic and only
realize it targets a particular driver only after opening the thread itself.

some people just look at the KSZ DSA driver all day, and so in their mind, it
then becomes implicit in the subject. But the cover letter description gets
turned by the netdev maintainers into a branch name for a merge commit, see:
fa15072b650a Merge branch 'sfc-devlink-support-for-ef100'
e9ab2559e2c5 Merge branch 'net-sched-transition-actions-to-pcpu-stats-and-rcu'
10d13421a6ae Merge branch 'net-core-commmon-prints-for-promisc'
a1d83abc8f2f Merge branch 'net-sched-retire-some-tc-qdiscs-and-classifiers'
and so, the naming of the cover letter has non-zero importance.
I agree that the contents of this patch set is absolutely disappointing
for someone reading the title and expecting some new ethtool counters.
