These counters have nothing to do with HW, they are from SW path. You're
either SW switching or getting some trash to control-plane.

You could do netdr or pinnacle or RP/SP ERSPAN capture to see what packets
are hitting control-plane

First step would be to compare 'show ibc | i packets/sec' between other box
which does not suffer from this, to confirm that packet rates are
unexpectedly high.
