When a virtual LAPB device's underlying Ethernet device closes, the LAPB device is also closed. However, currently the LAPB device is closed after the Ethernet device closes. It would be better to close it before the Ethernet device closes. This would allow the LAPB device to transmit a last frame to notify the other side that it is disconnecting.
