    can: dev: increase bus-off message severity · 71c23a82
    Jakob Unterwurzacher authored
    bus-off is usually caused by hardware malfunction or configuration error
    (baud rate mismatch) and causes a complete loss of communication.
    
    Increase the "bus-off" message's severity from netdev_dbg() to
    netdev_info() to make it visible to the user.
    
    A can interface going into bus-off is similar in severity to ethernet's
    "Link is Down" message, which is also printed at info level.
    
    It is debatable whether the the "restarted" message should also be
    changed to netdev_info() to make the interface state changes
    comprehensible from the kernel log. I have chosen to keep the
    "restarted" message at dbg for now as the "bus-off" message should be
    enough for the user to notice and investigate the problem.
