I'm testing out some code to get a stations's avg-signal through ethtool-stats,
and both it and /proc/net/wireless show ranges bouncing all over
(from around -48 to -110) on an interface running heavy traffic.
Are there any known bugs in 3.3.0 related to this?
Thanks,
Ben

As far as I know, this bug has always been there (RSSI values for A-MPDU
subframes are invalid, except for the last subframe).
I've sent fixes for this, which will show up in 3.4

I found the two patches and they apply cleanly to 3.3.0, and it
does appear to fix the problem.
Thanks,
