Never mind, that was my body being in a different time zone.
I went back and looked at a little chat i had with Patrick when he
posted with the macvlan driver.
At the moment we are still maintaining the model that a NIC can _only_
appear to have a single MAC to the upper layers. IOW, you have to
instantiate a macvlan device for each of the 16 MAC addresses on the
e1000 if you need to expose them. This means that the ip layer - even
with multiple ip addresses will only ever see one MAC address. 
Note also: The name macvlan is a little misleading since it allows for
the above without need for vlans.
