[openssl-users] Disable ETM in OpenSSL 1.1.0+

It appears that starting with OpenSSL 1.1.0, it is not possible to disable the Encrypt-Then-MAC (ETM) TLS extension for CBC ciphers. Is there an undocumented method to do this, which would also allow me to use the built-in s_server/s_client test mechanism?

Thanks,
-Mike
