why does Fedora's openssl not list "aesni" compared to RHEL?
the values below are showing it is in fact supported by both, on the
other hand "SSLCryptoDevice aesni" for Apache does not work on Fedora
and i am unsure if it is used automatically by default in that case
in doubt this may waste factor 8 in performance on modern hardware
