Subject: [ANN] netdev development stats for 6.2

Hi!

Here are the stats for the last release cycle (based on 18k emails
netdev has seen since Oct 3rd).

The methodology has not changed since the last time I shared those:
https://lore.kernel.org/all/20221004212721.069dd189@kernel.org/
I have now put the script up on GitHub for everyone to see / improve 
/ hack on: https://github.com/kuba-moo/ml-stat

When comparing the stats note that we had roughly 4k more messages,
partially due to the length of the analyzed period.

Like previously, please discount my "reviews" slightly as I send 
a lot of "process" emails..

The review count went up quite a bit for everyone but Krzysztof and
myself. Andrew remains firmly our top reviewer. We can see a
significant increase in participation from nVidia.

Where we count "authorship" by a fresh posting of a patch to the list.
So Saeed gets credit for all revisions of all patches that came thru
his tree, for example.


As for "scores" which are supposed to point out who doesn't help 
with reviewing (10 * reviews - 3 * authorship):

The positive section looks very much like the top reviewer section.

Kuniyuki has become an active reviewer of the socket layer (thanks!!)
therefore taking Amazon off the negative scores. Now the top three
negative scores belong to people sending semi-automated "bug fixes".

Significant increase in activity from nVidia, both in terms of
authorship (1.5x) and reviews (3x).

Huawei leads the pack in terms of patch bombardment with no real
participation. Interestingly Microchip remains in the #2 spot of 
the negative score list.
