Customer uses bondig + lacp + vlan for management/control-data interface
on their RHEL compute. The interface name is bond1.61, and its configuration file
is /etc/sysconfig/network-scripts/ifcfg-bond1.61.

Contrail version 2.21.2 build 36 /RHEL 7.1

During the installation of a vrouter, a provisioning script recreate the interface
configuration file mapped to vhost0, and it insert "HWADDR" entry to physical, and
"SUBCHANNELS" entry to bonding interface configuration.

https://github.com/Juniper/contrail-provisioning/blob/R2.21.x/contrail_provisioning/compute/network.py#L154
-----------------------------------------------------------------
        if os.path.isdir ('/sys/class/net/%s/bonding' % dev):
            bond = True
(snip)
        if bond:
            new_f_lines.append('SUBCHANNELS=1,2,3\n')
        else:
            new_f_lines.append('HWADDR=%s\n' % mac)
-----------------------------------------------------------------

Since the script doesn't distinguish whether the parent of vlan interface is bond or physical,
bond1.61 is regarded as non-bond interface and HWADDR is inserted to ifcfg-bond1.61.

However, it's problematic that the child interface configuration of bonding interface
has one of slave's MAC address as HWADDR. If the operating system recognize the other
slave first, mac address of bond interface can be different from that kept in configuration
file of child interface and thus it fails to be up.

If this happens during the last reboot after the setup_only_vrouter_node, the reboot_node
task is timed out and abort. So, the installation task should care whether the control-data
interface is a child of bonding interface.

Just install vrouter on RHEL compute that uses bondig + lacp + vlan for its control-data interface.

The issue is that HWADDR is inserted to the configuration file of vlan interface which is
a child of bonded interface. Provisioning script can detect parent bonded interface, but not
child of it.

Before the installation of vrouter, interface configuration is as below.

--------------------------------------------------
[root@lb3bp-vscp0001n ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens1f0

DEVICE="bond1.61"
ONBOOT="yes"
IPADDR="10.0.128.72"
NETMASK="255.255.255.192"
--------------------------------------------------

After the installation (running "fab reboot_node"), ifcfg-bond1.61 is changed to like this.

--------------------------------------------------
[root@lb3bp-vscp0001n ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond1.61
#Contrail bond1.61
DEVICE=bond1.61
TYPE="Vlan"
VLAN="yes"
DEFROUTE="yes"
ONBOOT="yes"
NM_CONTROLLED=no
HWADDR=8c:dc:d4:b7:41:20
--------------------------------------------------

HWADDR statement is inserted, and "8c:dc:d4:b7:41:20" is mac address of ens1f0.
This behavior is not desirable, so customer comment it out now.
