Hi Jiri

So i assume this means a frame ingressing on the switch port
enp3s0np19 matching the filter is now visible on the linux enp3s0np19
interface?  How do you avoid Linux processing it? If enp3s0np19 is a
member of a bridge, we don't want the software bridge processing it
and forwarding it out another port, since i assume the hardware has
already done this. Or does the trap stop further processing of the
frame by the hardware?

Thanks
      Andrew
