From 50efd403e67c6195a057417f8a2436d189c8dc81 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 1 Feb 2017 16:45:19 +0100 Subject: [PATCH] bcm53xx: set WAN MAC address to don't share one with LAN interface MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit After analyzing numerous NVRAMs and vendor firmwares it seems the base MAC address is used for LAN interface. WAN interface has different one which sometimes is set directly in NVRAM and sometines needs to be calculated.
