-Subject: [PATCH] Fix build with mbedtls w/o SSL renegotiation support
-
-In mbedtls, support for SSL renegotiation can be disabled at
-compile-time. However, OpenVPN cannot be built with such a library
-because it calls mbedtls_ssl_conf_renegotiation() to disable this
-feature at runtime. This function doesn't exist when mbedtls was built
-without support for SSL renegotiation.
-
-This commit fixes the build by ifdef'ing out the function call when
-mbedtls was built without support for SSL renegotiation.
