[ Upstream commit00b022f8f8] Some of the bcmgenet platforms don't correctly support WOL, yet ethtool returns: "Supports Wake-on: gsf" which is false. Ideally if there isn't a wol_irq, or there is something else that keeps the device from being able to wakeup it should display: "Supports Wake-on: d" This patch checks whether the device can wakup, before using the hard-coded supported flags. This corrects the ethtool reporting, as well as the WOL configuration because ethtool verifies that the mode is supported before attempting it.

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.
