ZyXEL NBG6817 - eth0 and eth1 MAC addresses changes randomly #10735

Open NilsRo opened 1 year ago

NilsRo commented 1 year ago

I facing the issue with OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.213.35964-87836ca, OpenWrt 22.03.0 r19685-512e76967f / LuCI openwrt-22.03 branch git-22.245.77528-487e58a and snapshot of 17.09.2022 for ZyXEL NBG6817 that the MAC addresses changes randomly for eth0 and eth1 after reboot.

My actual network configuration file is included and I opened a discussion https://forum.openwrt.org/t/zyxel-nbg6817-mac-is-set-on-virtual-devices-and-not-eth0-and-eth1/137353

Also I found a similar issue but different device and also correction, but perhaps they are linked: https://github.com/openwrt/openwrt/issues/9766#issuecomment-1248124941

I cannot see a similar behavior with my Netgear R7800 devices which have the same architecture. All MACs are stable and derived from eth0 and eth1.

Difference to Netgear R7800

The issue seems to be caused because the MAC is not assigned to eth0 and eth1 but to the virtual devices. This leads in my configuration that the MAC is lost. According my Netgear R7800 it should be assigned to the main device.

MAC is set differently to R7800, so this command should better set the MAC to the physical interfaces instead. https://github.com/openwrt/openwrt/blob/40874f0934973fd8a1b00de16db824a5b4ec75a9/target/linux/ipq806x/base-files/etc/board.d/02_network#L85-L91

ifconfig - Clean install

You can see that the MAC is assigned to virtual devices only.

The only difference in the system log between R7800 and Zyxel is the max address reported by the driver:

@NilsRo can you compile a custom image and test your implementation?

Actually I have no solution as with ucidef_set_interface_macaddr I cannot set a MAC to eth0 and eth1. I have to set this in the network configuration manually. So we need a function for ethX devices I ask in the forum for without response.
