Description of problem:

Setting MACADDR= in the network configuration file for an OVS bridge does not work as expected.  While the MAC address will be set initially, any OVS operation that changes *any* aspect of the OVS configuration will revert the MAC address to the one originally allocated to the bridge.

Version-Release number of selected component (if applicable):

    openvswitch-2.0.1-1.fc20.x86_64

How reproducible:

Create a configuration file /etc/sysconfig/network-scripts/ifcfg-br-test0 with the following contents:

    DEVICE=br-test0
    DEVICETYPE=ovs
    TYPE=OVSBridge
    ONBOOT=yes
    IPADDR=192.168.17.7
    NETMASK=255.255.255.0
    OVSDHCPINTERFACES=eth0
    MACADDR=c0:ff:ee:ee:ff:0c

Bring up the interface:

    # ifup br-test0

Examine the MAC address:

    10: br-test0: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default 
        link/ether c0:ff:ee:ee:ff:0c brd ff:ff:ff:ff:ff:ff

Make an unrelated OVS change:

    # ovs-vsctl add-br br-not-important

Examine the MAC address on br-test0 and see that it has changed:

    10: br-test0: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default 
        link/ether d2:2c:53:bb:16:46 brd ff:ff:ff:ff:ff:ff

Expected results:

I expect the MAC address set in the interface configuration file to
stick.

Additional info:

You can work around this problem right now by adding the following to
the interface configuration file:

    OVS_EXTRA="set bridge br-test0 other-config:hwaddr=$MACADDR"

However, I think that this should be handled automatically by ifup-ovs to avoid
the surprising behavior demonstrated here.
