Description Wen Liang 2022-04-12 15:35:45 UTC 
Description of the problem:

The following is the connection settings for `ib0-10`:

```network role
            network_connections:
              - name: ib0
                type: infiniband
                interface_name: ib0

              - name: ib0-10
                interface_name: ib0.000a
                type: infiniband
                autoconnect: yes
                infiniband:
                  p_key: 10
                  transport_mode: datagram
                parent: ib0
                state: up
                ip:
                  dhcp4: no
                  auto6: no
                  address:
                    - 198.51.100.133/30
                    - 2001:db8::2/32

```

Before bringing down the connection, the connection is active:
[root@wsfd-netdev23 ~]# nmcli c show --active
NAME    UUID                                  TYPE        DEVICE

[root@wsfd-netdev23 ~]# ip -d a s ib0.000a

    inet 198.51.100.133/30 brd 198.51.100.135 scope global noprefixroute ib0.000a
       valid_lft forever preferred_lft forever

    inet6 fe80::b41c:fee:35b1:fc43/64 scope link tentative noprefixroute 
       valid_lft forever preferred_lft forever



After bringing down the connection, the virtual infiniband device still exists:

[root@wsfd-netdev23 ~]# nmcli c down ib0-10
Connection 'ib0-10' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/17)
[root@wsfd-netdev23 ~]# ip -d a s ib0.000a

How reproducible:
I can reproduce every time  

Actual results:
Bring down the IP over infiniabnd connection will not remove the virtual infiniband device automatically 

Expected results:
Bring down the IP over infiniabnd connection should remove the virtual infiniband device automatically
