Hi, I'm currently trying to remove the dependency of label_mac in 02_network from phy setup, i.e. replacing stuff like $(cat /sys/class/ieee80211/phyX/macaddress) with extraction from the proper flash location.
One obstacle is the AVM FRITZ!WLAN Repeater 300E, where the calibration data is extracted with caldata_extract_reverse "urloader" 0x1541 0x440 Is there a sufficiently easy way to get the MAC address out of there _without_ relying on initialized Wifi? I'm looking for something like label_mac=$(some_extraction_function "urloader" <some_offset>) Technically, it should be somewhere in the reversed caldata, shouldn't it? If this is not possible (with reasonable effort), I would just calculate it based on the lan_mac in 02_network.

November 2019 00:32 To: openwrt-devel@lists.openwrt.org Subject: [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.
