    Bluetooth: bnep: Add support for get bnep features via ioctl · 0477e2e8

    This is needed if user space wants to know supported bnep features
    by kernel, e.g. if kernel supports sending response to bnep setup
    control message. By now there is no possibility to know supported
    features by kernel in case of bnep. Ioctls allows only to add connection,
    delete connection, get connection list, get connection info. Adding
    connection if it's possible (establishing network device connection) is
    equivalent to starting bnep session. Bnep session handles data queue of
    transmit, receive messages over bnep channel. It means that if we add
    connection the received/transmitted data will be parsed immediately. In
    case of get bnep features we want to know before session start, if we
    should leave setup data on socket queue and let kernel to handle with it,
    or in case of no setup handling support, if we should pull this message
    and handle setup response within user space.
