You can use the macvlan but the container <--> host communication won't

Yes, the virtualization begins at the network layer 2 and a virtual 
interface is created for the container.
Look at the lxc.conf man page and the doc/examples configuration files.

A quick start:

lxc-execute -n foo -s lxc.network.type=macvlan -s lxc.network.link=eth0 
-s lxc.network.flags=up -s lxc.network.ipv4= -- /bin/bash
