Since 24.10.0, eth0, used for the WAN interface, does not work. From dmesg: ... [ 1.831126] mt7530-mdio mdio-bus:1f: MT7530 adapts as multi-chip module [ 1.846204] mtk_soc_eth 1e100000.ethernet eth0: mediatek frame engine at 0xbe100000, irq 19 ...

[ 4.249680] mtk_soc_eth 1e100000.ethernet dsa: renamed from eth0 ... Like #15865, it seems that gmac0 does not rename eth0 to dsa until after the switch ports are initialized, leading to a name collision (error -17 = EEXIST). This patch follows #17062 by using openwrt,netdev-name to fix the collision. Signed-off-by: J. S.
