I have been having issues bridge devices, seems something has change. I can not use brctl or nmtui, I get a permission or a weird issue about vlan. If you are running into an issue where you can not setup a bridge device the old way this seems to work
ip link add br0 type bridge
ip link show type bridge
ip link set <device> master br0
ip link show dev br0
ip link set dev br0 up If an ip needs to be added do this
ip a add <xxx.xxx.xxx.xxx>/<netmask> dev <devname>example
ip a add 192.168.107.20/24 dev br0
