From a16edabe7f744b2d7a97bba4d4bc95b6894fd592 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 7 Oct 2015 21:45:42 -0700 Subject: [PATCH] net: eth: Clear MAC address in eth_pre_remove() platdata->enetaddr was assigned to a value in dev_probe() last time. If we don't clear it, for dev_probe() at the second time, dm eth will end up treating it as a MAC address from ROM no matter where it came from originally (maybe env, ROM, or even random). Fix this by clearing platdata->enetaddr when removing an Ethernet device.
