As I read it, the parameters are changed so the network stack knows this
packet came from the bridge device rather than from the enslaved interface
and that it should be passed up to higher layers. The dev is changed to
br->dev, the packet_type is changed to PACKET_HOST which means the packet is
to us, and we set the ethernet protocol type.
I hope this helps,
