    Subject[PATCH v1] Bluetooth: Return whether a connection is outbound
    From
    When an MGMT_EV_DEVICE_CONNECTED event is reported back to the user
    space we will set the flags to tell if the established connection is
    outbound or not. This is useful for the user space to log better metrics
    and error messages.
