Description of problem:

At the kubevirt project, we use guest agent reports in order to know the status of the guest interfaces.

For each interface that we configure for the guest (via domain XML), we have some additional parameters
outside of the guest (for example a custom name that comes from the virtual machine declarative spec).
By setting the MAC address in the domain XML, we are able to correlate the interface from the guest agent report
with those parameters from the vmi spec (having the MAC as the key).

The problem is that if a user in the guest changes the mac address of the interface,
we cannot use the MAC address as the key anymore.

How reproducible:

Always

Steps to Reproduce:
change the interface mac address
1. sudo ip link set dev eth0 address 02:00:b5:b5:b5:c9

Actual results:

the new interface mac is reported

Expected results:

both the new interface mac and the Permanent address should be reported in the interface entry
