I just upgrade from 3.10.58 to 3.14.22 and with later the problem seems
fixed. Using systemd-216.

A bit different, just in real hardware: static ip to br0 and attached
network card to br0.

$ cat /etc/systemd/network/br0.netdev
[NetDev]
Name=br0
Kind=bridge

$ cat /etc/systemd/network/br0.network
[Match]
Name=br0

[Network]
Address=192.168.0.77/24
Gateway=192.168.0.1

$ cat /etc/systemd/network/enp0s16.network
[Match]
Name=enp0s16

[Network]
Bridge=br0


In four cases (3.10.58 X 3.14.22) X (ip/brctl X networkd), the
difference is the macaddr of br0 as said in [#1], but now with
linux-3.14, even with a macaddr(br0) != macaddr(enp0s16) works fine.


Thanks.
