[OpenWrt-Devel] [PATCH 2/2] ath79: read label MAC address from flash instead of using phy0/phy1

This replaces all uses of $(cat /sys/class/ieee80211/phyX/macaddress)
by retrieval from the proper flash locations. This will make
02_network independent of WiFi setup again.

For the AVM FRITZ!WLAN Repeater 300E this replacement is non-trivial.
As it would be the only device in the whole trunk to keep the old
mechanism, this drops label MAC address for this device for now.

Is there an easy way to retrieve phy0 MAC address from fritz-300e?
Can it by deduced from the caldata extraction by assuming the
standard MAC offset after reverse?
