In PacketCapture, packets which don’t match the target BPF can be received after the socket is created and before the bpf filter is applied. This patch uses a zero bpf filter (matches no packet), then empties out any packets that arrived before the "zero-BPF" filter was applied. At this point the socket is definitely empty and it can’t fill up with junk because the zero-BPF is in place. Then we replace the zero-BPF with the real BPF we want.
