If userspace requests a feature which is not available the original set definition, then bail out with EOPNOTSUPP. If userspace sends unsupported dynset flags (new feature not supported by this kernel), then report EOPNOTSUPP to userspace. EINVAL should be only used to report malformed netlink messages from userspace.
