From 688cbaf202df8b4a69f5ccd39e0027f179852d44 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Sat, 2 Sep 2017 11:06:49 +0200 Subject: [PATCH] net: mvpp2: fallback using h/w and random mac if the dt one isn't valid When using a mac address described in the device tree, a check is made to see if it is valid. When it's not, no fallback is defined. This patches tries to get the mac address from h/w (or use a random one if the h/w one isn't valid) when the dt mac address isn't valid.
