i just tested your pr but cannot get the lan ports to work after booting the initramfs. i see the leds light up but no log message about link up in the logs and not dhcp response. even if i configure a static ip on the client i cant ping between devices.

are these changes (33197d22f0045b491ddea580bb2940a730918233, 4387de94454913aa79bb88971eabcf1bfca78141) applied to other asus devices also relevant to this one?

Mar 23 '25 13:03 achterin

@liudongdongdong7397 i just fixed all the issues i identified and added the changed @dangowrt suggested. lan ports do work now (also the labels are correct). mac addr are identical to vendor except like all the other asus devices the upper bit is also incremented. you can find the changes here: https://github.com/achterin/openwrt/commit/7987750cd4331ef96cf514c3c12f49b6b9d97821

Applied changes suggested by @achterin and @dangowrt. Tested, it's ok. Thank you.

@dangowrt anything else missing here to get this into main?

Apr 03 '25 06:04 achterin

@liudongdongdong7397 have you tried generating asuswrt compatible images? using https://github.com/openwrt/firmware-utils/blob/master/src/asusuimage.c by adapting these changes should be sufficient.
