J. S. Seldenthuis 4fed462454 ramips: use openwrt,netdev-name to fix port name conflict on TP-Link Deco M4R v4
Since 24.10.0, eth0, used for the WAN interface, does not work. From dmesg:

...

[    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.
