    mac80211: deprecate qual value · c27f2fde

    This value is unused by mac80211, because it was only
    be used by wireless extensions, and turned out to not
    be useful there because the quality value needs to be
    comparable between scan results and the current value
    which is impossible when the qual value is calculated
    taking into account noise, for example.
    
    Since it is unused anyway, this patch deprecates it
    in the hope that drivers will remove their sometimes
    quite expensive calculations of the value.
    
    I'm open to actual uses of the value, but the best
    way of using it seems to be what the Intel drivers do
    which should probably be generalised if we have noise
    values from the hardware.
