Does the Nginx HTTP/2 module work on RHEL 7.1 with (ALPN) TLS?

It seems like the HTTP/2 module is enabled by default in your RHEL 7.1
based rpm and srpm.

Your Nginx website writes about:

"Note that accepting HTTP/2 connections over TLS requires the
“Application-Layer Protocol Negotiation” (ALPN) TLS extension support,
which is available only since OpenSSL version 1.0.2. Using the “Next
Protocol Negotiation” (NPN) TLS extension for this purpose
(available since OpenSSL version 1.0.1) is not guaranteed. "

RHEL 7.1 is using OpenSSL 1.0.1e. with a whole bunch of patches and

Can't find anything in the changelog of RHEL 7.1's OpenSSL about ALPN.
The only thing i can find is "Support for Application Layer Protocol
Negotiation (ALPN) has been added." in RHEL's GnuTLS.
