From 9cfaf082b8775e9f99fa5f2e8b2ae0ca8baff785 Mon Sep 17 00:00:00 2001 From: Leonidas Da Silva Barbosa Date: Sat, 8 Aug 2015 18:31:01 -0300 Subject: crypto: nx - Removing CTR mode from NX driver CTR hardware implementation does not match with kernel spec causing a counter bug where just low 8 bytes are used for counter, when should be all 16bytes. Since we already have other counter modes working according with specs not worth to keep CTR itself on NX. Signed-off-by: Leonidas S.
