From 34afb764077768a361d76256fb05cbba172de223 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Fri, 21 Jul 2017 20:57:47 +0200 Subject: [PATCH] system-linux: fix GRE ikey/okey endianness The kernel expects IFLA_GRE_IKEY and IFLA_GRE_OKEY to be in network byte order, so convert the values from host byte order. Fixes ikey/okey on little endian systems.
