So what is your motivation for having this exposed through nl80211. For 
the average end-user the stats and parameters are fairly fuzzy. So can 
we expect some manual in which is described what parameter should be 
tweaked based on the retrieved statistics.

Also do you intend to remove the debugfs method? Seems a bit redundant 
to have two mostly identical interfaces in place.

Updating the nl80211.h in iw should be done with a copy from the kernel 
so it has to wait for the kernel patch to be applied (which tree I am 
unsure).
