This is based on an earlier patch from Eric Biederman adding forwarding between macvlans. I extended his approach to allow the administrator to choose the mode for each macvlan, and to implement a functional VEPA between macvlan. Still missing from this is support for communication between the lower device that the macvlans are based on. This would be extremely useful but as others have found out before me requires significant changes not only to macvlan but also to the common transmit path. I've seen one panic during testing this that I still need to track down, but it generally does what is advertised. I've tested VEPA operation with the hairpin support added to the bridge driver by Anna Fischer. My current plan is to submit this for inclusion in 2.6.33 when people are happy with it and I tracked down any remaining bugs, and possibly to do the communication with the lower device one release later.
