From cf953128e1663b0a96e6d6999c84b008a96fe394 Mon Sep 17 00:00:00 2001 From: Jeremy Compostella Date: Tue, 10 May 2016 11:53:06 +0200 Subject: [PATCH] libfec: pack the fec_header structure The fec_header structure is generated build time and stored on disk. The fec_header might be build on a 64 bits machine while it is read per a 32 bits device or the other way around. In such situations, the fec_header fields are not aligned as expected by the device and it fails to read the fec_header structure. This patch makes the fec_header packed.
