It is assigned in the driver, see at76c503.c, version 1.67, line 3269:

                                wstats->qual.qual    = buf->link_quality;
                                wstats->qual.level   = lev_dbm;
                                wstats->qual.noise   = buf->noise_level;
                                wstats->qual.updated = 7;

Unfortunately only the firmware for the (no longer sold, AFAIK) devices
with Intersil radios report the link quality. The RFMD devices report RSSI
only (uncalibrated :-(.

So this is a problem in the (binary only) firmware and/or of the radio
chipset.
