Subject: [PATCH 4.14 011/156] crypto: gcm - add GCM IV size constant
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Corentin LABBE <clabbe.montjoie@...il.com>
commit ef780324592dd639e4bfbc5b9bf8934b234b7c99 upstream.
Many GCM users use directly GCM IV size instead of using some constant.
This patch add all IV size constant used by GCM.
