Screenshot of bridge configuration

Description of problem:
Create bridge over two slaves in cockpit, if one of the slaves has the host connection, the status of bond and slaves are wrong.
1. If both two slaves are "ON" and have dhcp IP, the bridge over the two slaves can not get dhcp IP, and the two slaves are still "ON" with dhcp IP.
2. If only primary slave is "ON" and has dhcp IP, the bridge can get dhcp IP, but the primary slave is still "ON" with dhcp IP.

Expected results: Only bridge can get dhcp IP,  the slaves have NO dhcp IP automatically.


Version-Release number of selected component (if applicable):
redhat-virtualization-host-4.1-20180307.0
imgbased-0.9.54-0.1.el7ev.noarch
cockpit-ws-160-3.el7.x86_64
cockpit-ovirt-dashboard-0.10.10-0.el7ev.noarch
NetworkManager-1.10.2-13.el7.x86_64
glib-networking-2.50.0-1.el7.x86_64
libvirt-daemon-driver-network-3.9.0-13.el7.x86_64


How reproducible:
100%
Keywords: cockpit -> networking


Steps to Reproduce:

Scenario 1:
1. Install redhat-virtualization-host-4.1-20180307.0
2. Enable("ON") NIC1(eno1, can get dhcp ip: 10.73.130.225), connect host via cockpit:
   https://10.73.130.225:9090/network
3. Enter to networking page, enable("ON") NIC2(eno2, can get dhcp ip: 10.73.128.240),
4. Create bridge0 over the above two slave NICs(eno1, eno2)

Actual results:
1. After step 4, bridge0 can NOT get dhcp IP, but the two slaves are still connected with previous dhcp IP

Expected results:
1. After step 4, bridge0 can get dhcp IP, the two slaves should have NO dhcp IP automatically.

Scenario 2:
1. Install redhat-virtualization-host-4.1-20180307.0
2. Enable("ON") NIC1(eno1, can get dhcp ip: 10.73.130.225), connect host via cockpit:
   https://10.73.130.225:9090/network
3. Enter to networking page, check NIC2(eno2) is "OFF" with no dhcp IP
4. Create bridge0 over the above two slave NICs(eno1, eno2)

Actual results:
1. After step 4, bridge0 can get dhcp IP, but the slave(eno1) is still connected with previous dhcp IP

Expected results:
1. After step 4, the slave(eno1) should have NO dhcp IP. But change to bridge0 to be connected.


Additional info:
When both two slaves have DHCP ip, bridge can not get dhcp ip:
