                   'bond0': {'name': 'bond0',
                             'rxDropped': '0',
                             'rxErrors': '0',
                             'rxRate': '7.1',
                             'speed': '20000',
                             'state': 'up',
                             'txDropped': '0',
                             'txErrors': '0',
                             'txRate': '0.3'},

                   'ovirtmgmt': {'name': 'ovirtmgmt',
                                 'rxDropped': '0',
                                 'rxErrors': '0',
                                 'rxRate': '100.0',
                                 'speed': '1000',
                                 'state': 'up',
                                 'txDropped': '0',
                                 'txErrors': '0',
                                 'txRate': '5.5'}}

This may very well be a case of
    Bug 1120778 - align reported speeds for physical bond and bridge

but I'm not sure when we are going to fix it, since 3.6 vdsm reports absolute
rx/tx values, which lets Engine provide more sensible data to the user.
