tap(4): allow full-duplex and non-zero speed
tap(4) devices advertise themselves as just 'ethernet autoselect',
without duplex or speed capabilities.
This advertisement makes them unable to be aggregated into lacp-based
lagg(4):
- lacp code requires underlying interfaces to be full-duplex, else
interface will not participate in lacp at all
- lacp code requires underlying interface to have non-zero speed, else
this interface can not be selected as active aggregator
