Subject: ath5k negative RSSI?

Hello!

I'm looking at the RSSI values provided by the hardware in the RX descriptor
(rs_rssi) in ath5k. Sometimes the RSSI value is negative (-1, -2, -3) or zero
(0), which logically does not make sense. madwifi and ath9k work around
negative values by setting them to zero. Is this a known hardware bug? Or is
there anything we can do in the driver to get a more reliable RSSI value?

Thanks for any insights,
Bruno
