From 2e9f1bf5888b0df65a691bd10702f33193e9a666 Mon Sep 17 00:00:00 2001 From: Ioana Ciocoi Radulescu Date: Tue, 26 Feb 2019 15:50:07 +0000 Subject: [PATCH] driver: net: fsl-mc: Fix DPC MAC address fixup If node /board_info/ports does not exist in the DPC file, function mc_fixup_dpc() will skip not only MAC address fixup, but also the cache flush at the end. This may cause the other fixup changes (e.g. ICID related ones) to be ignored by MC.
