[ Upstream commit 00b022f8f876a3a036b0df7f971001bef6398605 ]
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.
Fixes: c51de7f397 ("net: bcmgenet: add Wake-on-LAN support code")

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.
