Add identifier for CID extension
Note: The current draft
does not yet specify the extension value, so we
use a temporary value of 42.
#define MBEDTLS_TLS_EXT_SESSION_TICKET 35
+/* The value of the CID extension is still TBD as of
+ * https://tools.ietf.org/html/draft-ietf-tls-dtls-connection-id-04. */
+#define MBEDTLS_TLS_EXT_CID 42 /* TBD */
+
#define MBEDTLS_TLS_EXT_ECJPAKE_KKPP 256 /* experimental */
#define MBEDTLS_TLS_EXT_RENEGOTIATION_INFO 0xFF01
