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. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S. Miller <davem@davemloft.net>
