Subject: [PATCH 3/3] ARM: dts: BCM5301X: Specify WAN port MAC address for Luxul XWR-3150

From: Rafał Miłecki <rafal@...ecki.pl>

It needs to be calculated based on the base Ethernet interface one.

This PATCH is a proof of concept that can go separately through the ARM
DT tree. I'd actually suggest that. There are more .dts files I'll want
to update.
Srini: can you just take the first 2 patches from this series?
