Hello,

I have added "--interpret-flow-packets"  to see what is happening,
does this options disables packet export? Anyway, I have tried to run
nprobe according to your advice with nflite plugin explicity enabled
(nprobe -i none --nflite 2055 -b 2), but it did not help - nprobe
shows 0 packets processed ; I can see that the switch sends templates
and frame slices roughly as expected (as far as I can tell -  i've
tried to dissect one manually).

# nprobe -i none --nflite 2055 -b 2
