For Envoy 3.0 the packet filter has the effect of stealing multicast/broadcast traffic from everybody. Reading the documentation and the implementation for the S2_PacketFilter hook feature, it is framed as an optimization, which it would have been if the client wouldn't have become the sole owner of the frame. Saying "no, it's not for me" to a frame is helpful, but saying "this looks interesting" ends up removing the frame has unexpected consequences. I wonder what purpose this behaviour could possibly have that makes sense?
Speed? It was created in another age with slow networks and slow computers, compared to today's world.
