From 806ffb1d504927d1449397377eac63bb63489266 Mon Sep 17 00:00:00 2001 From: John Holland Date: Thu, 18 Feb 2016 12:10:52 +0100 Subject: igb: allow setting MAC address on i211 using a device tree blob The Intel i211 LOM PCIe Ethernet controllers' iNVM operates as an OTP and has no external EEPROM interface [1]. The following allows the driver to pickup the MAC address from a device tree blob when CONFIG_OF has been enabled.
