-Subject: [PATCH] MIPS: BCM47XX: fixup broken MAC addresses in nvram
-
-The address prefix 00:90:4C is used by Broadcom in their initial
-configuration. When a mac address with the prefix 00:90:4C is used all
-devices from the same series are sharing the same mac address. To
-prevent mac address collisions we replace them with a mac address based
-on the base address. To generate such addresses we take the main mac
-address from et0macaddr and increase it by two for the first wifi
-device and by 3 for the second one. This matches the printed mac
-address on the device. The main mac address increased by one is used as
-wan address by the vendor code.
