+Subject: [PATCH] [mod_wolfssl] add complex preproc logic for SNI
+
+add complex preproc logic for SNI detection
+- HAVE_SNI is not sufficient
+- HAVE_LIGHTY is not sufficient (in wolfssl <= 4.5.0)
+Instead, use more complex logic wrapping calls to SNI_Callback()
+in wolfssl.
+
+x-ref:
+  "[lighttpd] -mod-wolfssl inhibited by missing library functionality"
+  https://github.com/openwrt/packages/issues/14142
+  "put all SNI code behind simpler preprocessor directive HAVE_SNI"
