I've tested git commit bf1594f54ea4b49eee95a16796ec11c55314b2a4.
Now eth0 is not configured at all:
$ ip l
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT
group default qlen 1000
link/ether 52:54:00:12:34:56 brd ff:ff:ff:ff:ff:ff
3: vlan0@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue
state UNKNOWN mode DEFAULT group default
link/ether 5e:69:2b:9a:93:07 brd ff:ff:ff:ff:ff:ff
So I can't test the original issue. That only occurs if eth0 gets an
address from the dhcp server.
The log looks like this:
