From f3edfd30541d6f245d7dfa6fa7354cc916cc53e1 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 15 Jun 2015 18:40:19 +0800 Subject: [PATCH] net: designware: Program MAC address to hardware after soft reset commit f566c99 "net: Update hardware MAC address if it changes in env" removes writing MAC address to designware controller after soft reset. This makes designware ethernet port fail to work. Actually the MAC address should always be programmed after soft reset.
