手动网络接口名称适用于 Wi-Fi，但不适用于以太网设备

我正在运行 Debian 9。我一直在关注本指南分配手动网络接口名称。我创建了两个文件：

$ cat /etc/systemd/network/20-wlan0.link 
[Match]
MACAddress=e0:94:67:0a:aa:f0

[Link]
Name=wlan0

$ cat /etc/systemd/network/50-eth0.link 
[Match]
MACAddress=3c:97:0e:06:f0:44

[Link]
Name=eth0

重新启动系统后，只有 Wi-Fi 卡的接口被重命名：

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s25: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000
    link/ether 3c:97:0e:06:f0:44 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether e0:94:67:0a:aa:f0 brd ff:ff:ff:ff:ff:ff

udevadm info -e向我展示：

哪里可以明显看出。关联文件已加载，但由于某些未知原因，接口未重命名。您知道出了什么问题以及如何调试吗？
