[systemd-devel] device state UNKNOWN

[arnaud gaboury]

Hi,

No idea why my bridge device, br0, has a state unknown.

$ ip addr
3: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UNKNOWN group default
    link/ether 66:73:a3:0a:44:f9 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.94/24 brd 192.168.1.255 scope global br0
       valid_lft forever preferred_lft forever
    inet6 fe80::6473:a3ff:fe0a:44f9/64 scope link
       valid_lft forever preferred_lft forever

$ systemctl status systemd-networkd

It seems to me that this device is configured, so why is its state
unknown  and not UP ? Shall I use a netctl profile to bring it UP,
like I do for enp7s0 ?
