virtual interface with macvlan

[Hyun Yoo <easetheworld () gmail com>]

Hello. Happy new year.

I'm trying to send a pcap file from linux machine A to B(directly
connected).

In machine A, I set up two virtual interfaces.
  # ip link add link eth1 eth1:1 address 11:11:11:11:11:11 type macvlan
  # ip link set eth1:1 up
  # ip link add link eth1 eth1:2 address 22:22:22:22:22:22 type macvlan
  # ip link set eth1:2 up
  # tcpdump -e -i eth1:1

In machine B, I send a pcap file which is a smtp session
between mac 11:11:11:11:11:11 and 22:22:22:22:22:22.
  # tcpreplay -i eth1 smtp.pcap

I expected that eth1:1 in machine A captures only
11:11:11:11:11:11-destined-packet.
but eth1:1 and eth1:2 always capture every packets.

What am I doing wrong?
