>Subject: [PATCH 1/4] lib: crypto: Add the ability to call AES implementations
> from libnettle.
>
>libnettle implements the AESNI Intel instruction set, so should be
>faster than our internal implementation if available on x86_64 and
>if compiled with --enable-fat to runtime select the correct instructions.
>NB. Currently on Debian (Debian version 9, codenamed stretch) and
>Ubuntu (17.04, codenamed Zesty Zapus) libnettle is *NOT* compiled
>to use --enable-fat, and so is *slower* than the Samba internal
>AES software functions.
>
>Add --accel-aes=[None|nettle|libnettle] to select at compile time.
>Default is None.
