    libertas: disable functionality when interface is down · d2e7b342
    Daniel Drake authored
    Modify the driver so that it does not function when the interface is
    down, in preparation for runtime power management.
    
    No commands can be run while the interface is down, so the ndo_dev_stop
    routine now directly does all necessary work (including asking the device
    to disconnect from the network and disabling multicast functionality)
    directly.
    
    power_save and power_restore hooks are added meaning that card drivers
    can take steps to turn the device off when the interface is down.
    
    The MAC address can now only be changed when all interfaces are down;
    the new address will be programmed when an interface gets brought up.
    This matches mac80211 behaviour.
    
    Also, some small cleanups/simplifications were made in the surrounding
    device handling logic.
