BUG reported by syzkaller. this patch will fix it in a way that the user is allowed to set llsec parameters for monitors but they will never use them because it's not supported. I resend my patch series which should forbid monitors to set any llsec parameters for now and the user will be aware that this feature isn't supported right now. Thanks. - Alex
