ethtool: add LINKMODES_NTF notification
Send ETHTOOL_MSG_LINKMODES_NTF notification message whenever device link settings or advertised modes are modified using ETHTOOL_MSG_LINKMODES_SET netlink message or ETHTOOL_SLINKSETTINGS or ETHTOOL_SSET ioctl commands. The notification message has the same format as reply to LINKMODES_GET request. ETHTOOL_MSG_LINKMODES_SET netlink request only triggers the notification if there is a change but the ioctl command handlers do not check if there is an actual change and trigger the notification whenever the commands are executed. As all work is done by ethnl_default_notify() handler and callback functions introduced to handle LINKMODES_GET requests, all that remains is adding entries for ETHTOOL_MSG_LINKMODES_NTF into ethnl_notify_handlers and ethnl_default_notify_ops lookup tables and calls to ethtool_notify() where needed.
