[f-nsp] Layer 2 packet forwarded in hardware(PP)

[Franz Georg Köhler]

I see on another device traffic hitting the CPU that looks like the same
packet hits twice with different reasons.
Does anyone have an idea why this happens?
I wonder why it is being claffied as multicast only once (and finally it
doesn't look like multicast)?
