[OpenWrt-Devel] [PATCH 3/6] ramips: mt7621: use flash location for wan_mac in 02_network

[Adrian Schmutzler]

This uses the flash locations instead of eth0 MAC address to
calculate MAC address increments for WAN.

The change will make the MAC address setup of a particular device
more obvious and removes the dependency of 02_network on the eth0
initialization.
