OpenSSL/Netty Setup

I am trying to setup OpenSSL. The documentation says to:

  1. Download netty-tcnative for RPM-based distributions ( _linux-x86_64-fedora.jar_ ) and place it into plugins/opendistro_security/ on every node.

I went to Netty: Downloads and netty-4.1.36.Final.tar.bz2 seems to be the latest to download. I unpacked it and can’t find any file that has linux-x86_64-fedora.jar in it. I really don’t know much about Netty or Mavin, and could really use some help.
