    libertas: submit RSSI command on tx timeout, to check whether module is dead
    We don't necessarily want to reset the device on a TX timeout. But more
    often than not, the real cause is that the firmware has crapped itself,
    not just that the network is busy. So submit any harmless command, and
    if _that_ times out, then the error handling code will reset the module,
    as appropriate.
