Kicinski: netdev in 2023

Networking maintainer Jakub Kicinski (along with several collaborators) has
put up a summary of
what happened in the kernel's network stack during 2023.

Throughout those releases netdev patch handlers (DaveM, Jakub,
Paolo) applied 7243 patches, and the resulting pull requests to
Linus described the changes in 6398 words. Given the volume of work
we cannot go over every improvement, or even cover networking
sub-trees in much detail (BPF enhancements… wireless work on WiFi
7…). We instead try to focus on major themes, and developments we
subjectively find interesting.
