QAT driver

[Neel Chauhan]

Hi,

This is great news for me with my home HPE ML110 G10/Xeon 4108 server.

However, I will not be able to test this patch unless it can get 
backported to 12.1 or 12.2 once it's out, and I don't expect backporting 
to happen.

I have one question about this: will I be able to use this to accelerate 
OpenSSL? Is additional code needed?

I use the mentioned HPE server for Tor and Tor is very crypto-heavy (yet 
singlethreaded).

I believe the official Intel drivers allow OpenSSL acceleration, but I'd 
prefer to avoid out-of-band drivers whether possible (ports/src is 
fine).
