Cannot get bridge up with systemd-networkd on C2 [SOLVED]

[graysky]

I need to use systemd-networkd to setup a bridge on my C2, but I get errors and no functional network. On my x86_64 box, this setup works fine, but on my C2 it does not work at all.

1. I have bridge-utils installed.
2. I have systemd-networkd and systemd-resolved enabled.
3. I setup the following 3 files in /etc/systemd/network
$this->bbcode_second_pass_code('', ' cat /etc/systemd/network/br0.network
[Match]
Name=br0
[Network]
DHCP=yes
')

$this->bbcode_second_pass_code('', '% cat /etc/systemd/network/br0.netdev
[NetDev]
Name=br0
Kind=bridge')

$this->bbcode_second_pass_code('', '% cat uplink.network
[Match]
Name=eth0
[Network]
Bridge=br0')

When the C2 boots, however, I get the following in the journalctl and no functional network. Any thoughts are appreciated.

$this->bbcode_second_pass_code('', '% journalctl -b -u systemd-networkd

')

Note - If I use a simple DHCP setup, the network works fine with systemd-netctld:
$this->bbcode_second_pass_code('', '% cat /etc/systemd/network/eth0.network
[Match]
Name=eth0
[Network]
DHCP=yes
')

Upstream blames the 3.14.x kernel...

Can anyone get either systemd-networkd or a netctl bridge working? Note that I can get the netctl bridge working, BUT when I try to let an lxc on the C2 use it, no network traffic in the lxc works at all.

I finally figured out a solution to this, see: https://github.com/graysky2/odroid-auto-bridge
