Lukas Wunner says:
====================
Polling be gone on LAN95xx
Do away with link status polling on LAN95xx USB Ethernet
and rely on interrupts instead, thereby reducing bus traffic,
CPU overhead and improving interface bringup latency.
Link to v2:
https://lore.kernel.org/netdev/cover.1651574194.git.lukas@wunner.de/
Only change since v2:
* Patch [5/7]:
* Drop call to __irq_enter_raw() which worked around a warning in
generic_handle_domain_irq(). That warning is gone since
792ea6a074 (queued on tip.git/irq/urgent).

====================
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.
