Rafał Miłecki 50efd403e6 bcm53xx: set WAN MAC address to don't share one with LAN interface
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.
