From b45714b164cac71f503ad73654b3c880cb9f2590 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Fri, 29 Mar 2019 21:16:23 +0100 Subject: [PATCH] xfrm: prefer family stored in xfrm_mode struct Now that we have the family available directly in the xfrm_mode struct, we can use that and avoid one extra dereference.
