[tor-relays] HW-Accelerated OpenSSL & Tor not playing nicely.

Thanks for your help. I left it out of my email, but I actually did do 
it. Except for the ls bit. I originally ran the config without "shared", 
encountered an error later down the road, deleted the extracted 
directory, and redid the config correctly, and then just simply did 
"sudo make" and then "sudo made install" without doing anything about 
the original library, which i assume was overwritten. But maybe I just 
corrupted it? Do I just delete the library's directory and retry, or is 
there something more?

  The "DUSE_CRYPTODEV_DIGESTS" is seen in the Tor error log because 
cryptodev digests are giving errors. I also don't see an entry about the 
"running the test suite" in the README. I see mention of a patch for 
Crytodev for OPENSSL, but, when on the site it links, I have no idea how 
to apply the patch for it says nothing patching it. (Sorry, I'm a total 
linux newb) Also, on the cryptodev-linux page: 
https://github.com/cryptodev-linux/cryptodev-linux/blob/master/NEWS , it 
says 1.7 was released in 07 Feb, 2015, which is long after the release 
of the patch that is talked about in the readme. Likewise, the patch 
linked is a whole year older than the version of OpenSSL I'm using, but 
it may not be part of the standard distribution of OpenSSL.

Also, I see the mention of GnuTLS in Crypodev, if there's a better way 
to go about having HW-accelerated crypto for Tor (excluding Intel 
aes-ni), please let me know.
