A little of both. The wireless statistics code in mac80211 has some strange conventions. I worked
for a while on improving it, but there are multiple opinions regarding the use of terms such as
"level" and "signal". After a few tries, I dropped that part and made bcm43xx-mac80211 conform to
the mac80211 conventions. Now there are lines like "Link Quality=77/100 Signal level=-49 dBm Noise
level=-73 dBm" in the iwconfig output. These values look reasonable.
