-This patch adds support for TLS SessionTicket extension (RFC 5077) for
-the parts used by EAP-FAST (RFC 4851).
-
-This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
-(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
-
-NOTE: This patch (without SSL_set_hello_extension() wrapper) was
-merged into the upstream OpenSSL 0.9.9 tree and as such, an external
-patch for EAP-FAST support is not needed anymore.
