I'm configuration my modem using the qmi protocol, my modme unable to properly registered in some environment, resulting in qmi dial-up connection will fail, at this point, the netifd frequently attempt reconnection, each a reconnection failure will be ifup-failed signal, I can ignore the signals in the hotplug, but I don't want to do so, I just need to reduce its frequency, what parameters can alter the frequency of netifd retry?
