*
* Enable support for RFC 8446 TLS 1.3 early data.
*
* Requires: MBEDTLS_SSL_SESSION_TICKETS and either
* MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_PSK_ENABLED or
* MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_PSK_EPHEMERAL_ENABLED
* Requires: MBEDTLS_SSL_SESSION_TICKETS
*
* Comment this to disable support for early data. If MBEDTLS_SSL_PROTO_TLS1_3
* is not enabled or both MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_PSK_ENABLED and
* MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_PSK_EPHEMERAL_ENABLED are disabled or
* MBEDTLS_SSL_SESSION_TICKETS is not enabled, this option does not have any
* effect on the build.
* MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_PSK_EPHEMERAL_ENABLED are disabled,
* this option does not have any effect on the build.
*
* This feature is experimental, not completed and thus not ready for
* production.
