无法找出创建虚拟网络设备的原因

因此，由于某种原因，我有一堆命名的虚拟网络设备br-XXXXXXXXXXXX，但我不知道是什么创建了它们。

user@device:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

我想删除这些虚拟设备，因为它们占用了172.XX.0.0/16子网，导致我的设置出现一些网络问题。

我已经尝试单独删除所有这些虚拟设备，sudo ip link delete <devicename>但它们在重启后又会重新出现。

Ubuntu 20.04.2 LTS（桌面版）上发生的事情
