DO NOT FOCUS I add the function of set cipher-suite, but does not work.

[jesson3264]

I used openssl, compiled with -DMG_TLS=2, and I add some code in function : mg_tls_init.
The ciper suites value is : ECDHE-RSA-AES256-GCM-SHA384

MG_ERROR(("ciphersuites:%s",opts->cipher_suites.buf));
 // set cipher-list
  if (opts->cipher_suites.buf && 
      SSL_set_cipher_list(tls->ssl, opts->cipher_suites.buf) != 1) {
    MG_ERROR(("set cipher suites failed.%d", errno));
    goto fail;
  }

I used tcpdump to capture packages, But the server always used the Cipher Suite: TLS_AES_128_GCM_SHA256 (0x1301).

Does I code the wrong place ?
