This reverts commit108a36d07c. It was reported that this fix breaks the possibility to remove existing WoL flags. For example: ~$ ethtool lan2 ... Supports Wake-on: pg Wake-on: d ... ~$ ethtool -s lan2 wol gp ~$ ethtool lan2 ... Wake-on: pg ... ~$ ethtool -s lan2 wol d ~$ ethtool lan2 ... Wake-on: pg ... This worked correctly before this commit because we were always updating a zero bitmap (since commit6699170376("ethtool: fix application of verbose no_mask bitset"), that is) so that the rest was left zero naturally. But now the 1->0 change (old_val is true, bit not present in netlink nest) no longer works.

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.
