A few PHY drivers are currently attempting to not suspend the PHY when Wake-on-LAN is enabled, however that code is not currently executing at all due to an early check in phy_suspend(). This prevents PHY drivers from making an appropriate decisions and put the hardware into a low power state if desired. In order to allow the PHY drivers to opt into getting their ->suspend routine to be called, add a PHY_ALWAYS_CALL_SUSPEND bit which can be set. A boolean that tracks whether the PHY or the attached MAC has Wake-on-LAN enabled is also provided for convenience. If phydev::wol_enabled then the PHY shall not prevent its own Wake-on-LAN detection logic from working and shall not prevent the Ethernet MAC from receiving packets for matching.

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.
