From d14e7e7b5b3e21b26b6527753313d441a257941f Mon Sep 17 00:00:00 2001 From: Konstantin Ananyev Date: Tue, 2 Apr 2019 09:34:38 +0100 Subject: [PATCH] ipsec: change order in filling crypto op Right now we first fill crypto_sym_op part of crypto_op, then in a separate cycle we fill crypto op fields. It makes more sense to fill whole crypto-op in one go instead.
