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.
