ethtool: add WOL_NTF notification
Send ETHTOOL_MSG_WOL_NTF notification whenever wake-on-lan settings of
a device are modified using ETHTOOL_MSG_WOL_SET netlink message or
ETHTOOL_SWOL ioctl request.
As notifications can be received by anyone, do not include SecureOn(tm)
password in notification messages.
