So is this per-frame information if the internal registers are read out right after receiving a frame, or is it always an aggregate over several received frames? > I think AR9380 and later support what you saw in that paper - where > you request that you get CSI data as part of some receive frame.

Nevertheless, I plan to use AR9590 and/or AR9390 cards so I guess that these meet the criterion of "AR9380 and later".
