In the current PSE interface for Ethernet Power Equipment, support is limited to PoDL. This patch extends the interface to accommodate the objects specified in IEEE 802.3-2022 145.2 for Power sourcing Equipment (PSE). The following objects are now supported and considered mandatory: - IEEE 802.3-2022 30.9.1.1.5 aPSEPowerDetectionStatus - IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState - IEEE 802.3-2022 30.9.1.2.1 aPSEAdminControl To avoid confusion between "PoDL PSE" and "PoE PSE", which have similar names but distinct values, we have followed the suggestion of Oleksij Rempel and Andrew Lunn to maintain separate naming schemes for each, using c33 (clause 33) prefix for "PoE PSE".

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 reStructuredText 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.
