Interfaces assigned to a bridge should not be allowed to be deleted. If an interface is deleted from the config, the subsequent boot will fail with a configuration error as one of the bridge interfaces is mirring.
This is true for the following interfaces:
* bonding
* dummy
* geneve
* l2tpv3
* loopback
* openvpn
* pppoe
* pseudo-ethernet
* tunnel
* vti (to be done on interface rewrite)
* vxlan
* wireguard
* wireless
* wirelessmodem
