[systemd-devel] sshd.service fails on boot when primary listener is a bridge (br0) instead of real interface (eth0). What dependency is needed?

[lyndat3]

My /etc/systemd/system/sshd.service has a

  After=network-online.target

dependency.

When my ethernet interface, eno1, is the primary 'net listener,

        cat /etc/sysconfig/network/ifcfg-eno1
                STARTMODE='auto'  
                BOOTPROTO='static'
                IPADDR='192.168.1.1/24'

sshd, listening on 192.168.1.1, has no problems on boot.

But, if I switch to using a bridge interface, br0, with eno1 as the real 
interface assigned to it,

        cat /etc/sysconfig/network/ifcfg-eno1 
                STARTMODE='auto'
                BOOTPROTO='none'

        cat /etc/sysconfig/network/ifcfg-br0
                STARTMODE='auto'
                BOOTPROTO='static'
                BRIDGE='yes'
                BRIDGE_PORTS='eno1'
                IPADDR0='192.168.1.1/24'

sshd fails on boot

        journalctl -b | grep -i sshd
                ...
                Apr 10 15:30:49 xen01 sshd[1345]: error: Bind to port 22 on 
192.168.1.1 failed: Cannot assign requested address.
                ...

Apparently, network-online waits for *real* interfaces only.

Once at the shell, br0 is fully up.  sshd can be started, and it functions 
normally.

What dependency do I need to add to my sshd unit to get it to wait for br0 
being fully up?
