    cxgbe(4): Allow tracing filters on loopback ports.
    
    Each physical port has an associated loopback tx channel and anything
    transmitted over that channel by the driver is looped back internally by
    the hardware as if received on that physical port.  This change allows
    tracing filters to be installed in this loopback path.
