From 387cbf096e443705fa66776027273ed257ec6ca3 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 18 Aug 2020 08:19:02 -0500 Subject: [PATCH] net: smc911x: Automatically Update ethaddr with MAC The ethernet controller can read the MAC from EEPROM and display it, but if ethaddr is not set, the ethernet is still unavailable. This patch checks will automatically set the MAC address if it has not already been set.
