The number being passed into ssi is dBm, so why is the max being set to 60? It
should be set to the minimum dBm that the device can report, like -110 as it
was set before. Since SSI is actually being passed into signal, MAX_SSI
should go to max_signal.
You are correct that -110 would be better than -196, which is what 60 translates to given the s8
arithmetic. Due to the internal workings of mac80211, the quantity in max_signal ends up as the
denominator in the qual report of x/y. I would sooner give the users a percentage that parts per 60.
