A bitset without mask in a _SET request means we want exactly the bits in
the bitset to be set. This works correctly for compact format but when
verbose format is parsed, ethnl_update_bitset32_verbose() only sets the
bits present in the request bitset but does not clear the rest. This can
cause incorrect results like
lion:~ # ethtool eth0 | grep Wake
Supports Wake-on: pumbg
Wake-on: g
lion:~ # ethtool -s eth0 wol u
lion:~ # ethtool eth0 | grep Wake
Supports Wake-on: pumbg
Wake-on: ug
when the second ethtool command issues request
ETHTOOL_MSG_WOL_SET
ETHTOOL_A_WOL_HEADER
ETHTOOL_A_HEADER_DEV_NAME = "eth0"
ETHTOOL_A_WOL_MODES
ETHTOOL_A_BITSET_NOMASK
ETHTOOL_A_BITSET_BITS
ETHTOOL_A_BITSET_BITS_BIT
ETHTOOL_BITSET_BIT_INDEX = 1
Fix the logic by clearing the whole target bitmap before we start iterating
through the request bits.

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.
