It is not possible to determine the active TLS mode from the presence or absence of sysfs attributes like tls_key, tls_configured_key, or dhchap_secret. With the introduction of the concat mode and optional DH-CHAP authentication, different configurations can result in identical sysfs state. This makes user space detection unreliable. Read the TLS mode used from the newly added sysfs entry. Signed-off-by: Daniel Wagner <wagi@kernel.org>
