Log message:
Avoid netlock dance in cad(4) ioctl.
While interface ioctl(8) is moving towards better parallel access,
drivers assuming exclusive netlock and unlocking explicitly cause
trouble. Use the drivers own configuration lock for protection.
Do not wait for task barriers while potentially holding the netlock.
Panic reported by Mark McBride and Thomas Pries.
