Unfortunately, the link quality is not reported uniformly by drivers.
Some only give you the signal level in dBm, many give you noise in dBm
(so at least one could do a signal-to-noise ratio for some idea of
quality), some drivers give you a quality but no maximum quality, and
some drivers actually do the right thing.  Furthermore, many drivers
don't report the correct maximum quality/max rssi for your particular
chipset.  Its really not good to rely on anything quality related at
this time.
