It does include CCA/noise. No idea about VCS/NAV. I thought it was
controlled by a line from the BB (RX_CLEAR) rather than VCS/NAV, which
is a MAC counter function. But I could be wrong.
I've punted the question internally; I'll post back when I have more details.
These can be easily tested though - just fake some NAV entries and see
if your busy counters go up.
