From 43bfc499925ee1f49355974409808a227cb4f9a0 Mon Sep 17 00:00:00 2001 From: Bhuvanchandra DV Date: Mon, 25 Mar 2019 17:18:28 +0100 Subject: [PATCH] toradex: common: unify behaviour when config block is missing If the config block is missing, various things may fail or behave strangely on certain modules. This patch unifies that behaviour by using a fake MAC address, until user updates the config block.
