Works like a charm with Debian kernels >2.6.28:

piper:~# ip link add link lan address 02:34:22:ef:a2:c3 pseudo type macvlan

piper:~# ip link show pseudo
117: pseudo@lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether 00:34:22:ef:a2:c3 brd ff:ff:ff:ff:ff:ff

 nation that is attacked, and every man will be glad of those
 conscience-soothing falsities, and will diligently study them, and
 refuse to examine any refutations of them; and thus he will by and by
 convince himself that the war is just, and will thank god for the
 better sleep he enjoys after this process of grotesque
 self-deception."
