+Subject: [PATCH] Use wolfSSL for TLS
+
+Changes:
+- `config.mk`: add the `WITH_TLS=wolfssl` option
+- The`wolfssl/options.h` header is included by defining the `EXTERNAL_OPTS_OPENVPN` macro
+- `net_mosq.c`: UI_METHOD not implemented in wolfSSL
+- `net_mosq.h`: UI_METHOD not implemented in wolfSSL
+- `net_mosq_ocsp.c`: safestack.h not implemented in wolfSSL
