尝试设置网络绑定，然后使用 netplan 在桥接中使用该绑定。绑定在 proc 下正确显示，但拉动以太网不会导致故障转移到 Wi-Fi。我的 netplan 配置文件如下：
# Let NetworkManager manage all devices on this system

version: 2
renderer: networkd
ethernets:
enp1s0:
dhcp4: true
dhcp6: no

如果我不使用网桥，而只是为系统配置一个绑定，它将正确启动并按预期运行，即拔下以太网会强制连接到 Wi-Fi，然后在恢复以太网后切换回来。但是当我将网桥设置为使用 bond0 时，故障转移不再起作用，并且只有在插入以太网时才能 ping 接口。

我尝试过从 networkd 切换到 NetworkManager，尝试过有或没有 VLAN 配置。任何帮助都将不胜感激。
