Description omergi 2019-12-29 17:20:24 UTC 
Description of problem:
When trying to get the mac address of an ovs-interface or ovs-bridge with NetworkManager it is shown as (unknown).

Version-Release number of selected component (if applicable):
NetworkManager-1.18.0-5.el7_7.1.1.bz1740557.x86_64
NetworkManager-1.20.8-1.fc31.x86_64
NetworkManager-1:1.14.0-14.el8.x86_64

How reproducible:
Create ovs-bridge, ovs-port and ovs-interface.
Get interface and bridge mac address with nmcli

Steps to Reproduce:
nmcli conn add type ovs-bridge \
    connection.id mybr \
    connection.interface-name mybr
nmcli conn add type ovs-port \
    connection.interface-name mybr-port0 \
    master mybr
nmcli connection add type ovs-interface \
    connection.id mybr1 \
    connection.interface-name mybr1 \
    master mybr-port0 


Actual results:
ip a:
mybr1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
