Subject: [PATCH] Fix compilation against linux 4.3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Linux Crypto API changed to using aead_request_set_ad()
instead of aead_request_set_assoc().

Based on Horia Geantă's patch from
https://mail.gna.org/public/cryptodev-linux-devel/2015-11/msg00002.html

However we need to version-guard the change for older versions of the
kernel to avoid the build from breaking for them.
