It's not a bug, it was just not implemented yet.

The macvlan mode you are talking about is the macvlan bridge mode. This
mode is explained in the lxc.conf (5) man.
It was recently merged upstream and should be available for the 2.6.33
kernel.
If you want to enable this mode in lxc, you have to specify:
lxc.network.type=macvlan
lxc.network.macvlan.mode=bridge
...
This mode will allow several macvlan to communicate if they have the
same lower-dev (eg eth0).
But this mode does not allow macvlan<->eth0 communication, you have to
create a macvlan in the host.
