This commit works around this behaviour by setting the MAC addresses during the preinit phase. The same has been implemented recently for the Siemens WS-AP3610 in d2b8ccb1c04d ("ath79: add support for Siemens WS-AP3610"). MAC assignment in vendor firmware is as follows: use vendor address OpenWrt 2g wifi0 ethaddr -> wlan1 5g wifi1 ethaddr +1 -> wlan0 lan eth1 ethaddr +2 -> eth0 wan eth0 ethaddr +3 -> eth1 ethaddr is retrieved by $(mtd_get_mac_ascii u-boot-env ethaddr) Note that both Wifi and ethernet indexing is swapped in OpenWrt compared to vendor firmware.
