From 85aef6f627040cd0909bd549abb721eafa511353 Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Tue, 7 Apr 2020 12:31:48 +0200 Subject: [PATCH] ath79: fix MAC addresses for ethernet on ZyXEL NBG6716 MAC addresses of the ethernet devices (eth0 & eth1) are randomly set at boot time by the ag71xx driver, because it is currently not possible to retrieve MAC addresses in ASCII format within the DTS file. 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.
